Iridescent bugs: The science behind nature?s bling 2011-05-16T23:39:00Z It is quite a mistake to suppose that, apart from the chlorophyll function, the physiology of the fungus-cell is fundamentally different from that of ordinary plant-cells. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z Probably the more intense light of India enables the corpuscles to flourish in situations in which in Europe they would lose their chlorophyll. Freshwater Sponges, Hydroids & Polyzoa 2011-06-25T02:00:17.833Z Particles of light called photons, streaming down from the Sun, arrive randomly at the chlorophyll molecules and other light-absorbing 'antenna' pigments that cluster inside the cells of every leaf, and within every photosynthetic bacterium. Physics of life: The dawn of quantum biology 2011-06-15T17:20:25.507Z The latest results place the maximum assimilation in the red-orange, and this coincides with the maximum absorption in the chlorophyll. Disease in Plants 2012-03-01T03:00:22Z The signal varies depending on the leaves' concentrations of nutrients, minerals, pigments such as chlorophyll, and the compounds that plants use to protect themselves against the Sun and predators. A new eye on biodiversity 2011-06-01T17:20:20.113Z However, physical drivers such as light supply, nutrient supply, and stratification are known to have an extremely important role on determining phytoplankton chlorophyll – dominating it on seasonal to inter-annual time scales. Dot Earth: On Plankton, Warming and Whiplash 2011-04-26T19:04:43Z Judging by the amount of chlorophyll, I would imagine that there will be quite a lot. The Catlin Arctic Survey: A Melting Ocean 2011-04-20T13:45:00.257Z The yeast plant and its allies are saprophytes and form no chlorophyll. Encyclopaedia Britannica, 11th Edition, Volume 10, Slice 3 "Fenton, Edward" to "Finistere" 2011-03-14T03:01:00.580Z For cholera, they could look at sea surface height and levels of the green pigment chlorophyll, because cholera bacteria spend much of their life attached to a floating animal that feeds on chlorophyll-filled plants. Tracking Disease From Outer Space 2011-02-25T19:20:00Z Researchers are hoping that the Seagliders' three optical sensors shed light on the water's biological properties, including the amount of oxygen and the presence of chlorophyll. Bloom with a View: Robot Subs Help Researchers Study Mysterious Antarctic Sea Life [Slide Show] 2011-02-25T11:15:00.230Z Concerning your question about the confidence I have in Boyce et al.’s original conclusions: I have no confidence that the analysis demonstrated a global, long-term decline in chlorophyll over the centennial scale. Dot Earth: On Plankton, Warming and Whiplash 2011-04-26T19:04:43Z But for that magician chlorophyll, conjuring with sunbeams, such things as animal life and conscious intelligence would be impossible; there would be no problems of creation, nor philosopher to speculate upon them. Through Nature to God 2010-12-24T03:00:36.410Z “This is a very important new development, and is the first new type of chlorophyll discovered in an oxygenic organism in 60 years,” says biological chemist Robert Blankenship of Washington University in St. Louis. Chlorophyll Gets an ?f? 2010-08-23T14:29:00Z The CTD, shorthand for conductivity, temperature and depth, measures — you guessed it — conductivity, temperature and depth, as well as chlorophyll and oxygen levels. Meet Alvin, the Deep-Sea Submersible 2010-08-04T16:49:00Z Alfred E. Treibs, a German chemist, discovered that oil harbored the fossil remains of chlorophyll, the compound in plants that helps convert sunlight into chemical energy. Tracing Oil Reserves to Their Tiny Origins 2010-08-02T22:33:00Z Over this shorter time period, sampling has been comprehensive enough to accurately estimate chlorophyll variability related to climate phenomena. Dot Earth: On Plankton, Warming and Whiplash 2011-04-26T19:04:43Z In photosynthesis, microbes or plants containing chlorophyll grow by gleaning energy from the sun, releasing oxygen as a waste product. Bacteria Show New Route to Making Oxygen 2010-03-25T13:32:00Z The newfound pigment, dubbed chlorophyll f, absorbs light most efficiently at a wavelength around 706 nanometers, just beyond the red end of the visible spectrum, researchers report online August 19 in . Chlorophyll Gets an ?f? 2010-08-23T14:29:00Z The batches were actually concoctions of sunflower oil mixed with industrial chlorophyll. 2010-02-13T14:29:00Z The technology uses a photosensitive dye to start its energy production, much the way leaves use chlorophyll to begin photosynthesis. 2010-01-30T19:40:00Z In nature this reduction is accomplished by the radiant energy of the sun, by the agency of the catalytic action of chlorophyll. The Mechanism of Life When light is absorbed by the chlorophyll of green plants, one of the initial reactions is a transfer of hydrogen from water to a triphosphopyridine nucleotide, which later acts to reduce the carbon dioxide. History of Phosphorus Previously there were four known chlorophylls made by plants and other photosynthesizing organisms that generate oxygen: a, b, c and d. Chlorophyll Gets an ?f? 2010-08-23T14:29:00Z The Corky Layer or Outer Bark, the cells of which contain no chlorophyll, and are of the nature of cork. The Elements of Botany For Beginners and For Schools Whatever relation magnesium may have to fat-formation, or to the translocation of phosphorus, it is evident that these are rôles quite apart from its use as a constituent element in chlorophyll. The Chemistry of Plant Life The energy of the solar radiations is absorbed by the chlorophyll of the leaves, and stored up in the organic carbohydrates formed by the synthesis of water and carbon. The Mechanism of Life This function is performed by the leaves which contain the green colouring-matter known as chlorophyll, the presence of which is essential to the course of the chemical changes. Coal and What We Get from It Chlorophylls b and c are found in fewer organisms and absorb light in a similar range as chlorophyll a does, but shifted a bit. Chlorophyll Gets an ?f? 2010-08-23T14:29:00Z Under the light of the sun, acting upon green parts or foliage, that is, upon the chlorophyll, or upon what answers to chlorophyll, which these parts contain. The Elements of Botany For Beginners and For Schools Under the ordinary conditions of temperature, moisture supply, etc., necessary to plant growth, photosynthesis will take place if the three essential factors, chlorophyll, light, and carbon dioxide are available. The Chemistry of Plant Life All these complex bodies are stores of energy; the vital processes of oxydation do but liberate in the human body the energy which the chlorophyll of plants has absorbed from the solar rays. The Mechanism of Life Botanists unite in describing the plants of this class as being destitute of chlorophyll and of starch. Student's Hand-book of Mushrooms of America, Edible and Poisonous Chlorophyll d, found in a specific group of cyanobacteria, absorbs the most light at roughly 697 nanometers, a slightly shorter wavelength than the absorption of the new chlorophyll. Chlorophyll Gets an ?f? 2010-08-23T14:29:00Z Others, of a kind which is very common in fresh water, simple threads made of a line of cells, have the chlorophyll and protoplasm of each cell arranged in spiral lines or bands. The Elements of Botany For Beginners and For Schools Trehalose appears to replace sucrose in those plants which contain no chlorophyll and do not elaborate starch. The Chemistry of Plant Life Moreover, there are intermediary forms, such as fungi, which possessing no chlorophyll are nourished like animals by organic matter, and yet like vegetables are able to manufacture organic matter from mineral salts. The Mechanism of Life Out of the morning rainbow dropped a swarm of winged lizards, twenty feet in length and a glistening chlorophyll green in the early light. The Anglers of Arz If it is chlorophyll, either Cleve is right or else he's discovered a new class of arthropods. Tabby They contain chlorophyll, but the green colour is masked by the presence of diatomin, a brown pigment which resembles that which occurs in the Brown Algae or Phaeophyceae. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 4 "Diameter" to "Dinarchus" As has been said, this alcohol occurs nowhere else in nature, and its presence and function in the chlorophyll molecule are, as yet, wholly unexplainable. The Chemistry of Plant Life The combination of carbon with water carried out by the agency of chlorophyll can only take place with absorption of energy. The Mechanism of Life He eats dandelions, parsley, grass, eh ... chlorophyll, obviously. The Buttoned Sky They grow incredibly fast with a little sun, so the chlorophyll is biologically justified in the life-cycle. Tabby No direct connexion has been traced between the chlorophyll eaten with the food and the haemoglobin of blood and muscle. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 6 "Cockaigne" to "Columbus, Christopher" In all of these compounds, derived from chlorophylls by the action of alkalies, the Mg remains in the molecule, and all the Mg-containing derivatives from the chlorophylls are known as "phyllins." The Chemistry of Plant Life This energy comes directly from the sun, the red and orange light radiations being absorbed by the chlorophyll. The Mechanism of Life Evidently they draw nourishment out of the human bodies—all that chlorophyll makes me think it's a definitely physical nourishment, rather than a psychic one. The Buttoned Sky Cleveland now rests his extraterrestrial origin theory on an idea that the green stuff is chlorophyll. Tabby But how the chlorophyll makes use of these to effect the breaking up, and how it starts the subsequent syntheses of the carbon into the most complex organic compounds remains a mystery. Naturalism And Religion In this way, a whole series of compounds, corresponding to each of the chlorophylls and their alkali-decomposition products, but with the magnesium lacking in each case, has been prepared. The Chemistry of Plant Life "You will find that the streets actually are filled with chlorophyll," the vine said. Collector's Item It's impossible to synthesize chlorophyll from the light rays given off by our sun—only cyanophyll. The Venus Trap But it was tricky stuff; one part in ten-million would destroy the chlorophyll in plants in about twenty hours, or the hemoglobin in blood in about fifteen minutes. Let'Em Breathe Space The gentle fanning of their branches has eased my pain-racked brow and given me much-needed sleep, whilst the chlorophyll of their leaves has acted like balm to my eyelids, inflamed after long hours of study. Byways of Ghost-Land Indeed, it was the production of these compounds which led to the discovery of the existence of the two chlorophylls. The Chemistry of Plant Life Is it true that the streets are filled with chlorophyll? Collector's Item The plant can go to inorganic nature and through its chlorophyll can191 draw the sustenance from it. Under the Maples Abundant plant food supplies more chlorophyll or green coloring matter to the sap also. The Mayflower, January, 1905 Large groups of the simpler animals contain chlorophyll, and decompose carbonic acid under the influence of light, as plants do. Essays: Scientific, Political, & Speculative, Vol. I Thus, it would appear that the unit structural groups in hæmatin and in chlorophyll are identical; although chlorophyll may exhibit more variations in isomeric arrangement of these structural units than have been found in hæmatin. The Chemistry of Plant Life The part of the plant that can put carbon dioxid and water together is the green stuff or chlorophyll, and this can work only when light is shining on it. Common Science The secondary men go to books and creeds and institutions for their religion, but the original men, having the divine chlorophyll, go to Nature herself. Under the Maples All fungi are either parasites or saprophytes which have lost their chlorophyll, and are incapable of supporting an independent existence. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth The schizomycetes or bacteria are minute vegetable organisms Definition. devoid of chlorophyll and multiplying by repeated bipartitions. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" Solutions of the chlorophylls are fluorescent, being green by transmitted, and red by reflected light. The Chemistry of Plant Life When the sun shines on chlorophyll, the green substance in plants, the chlorophyll puts them together and makes sugar. Common Science It seems to be directly dependent, in some way or other, on the chlorophyll, or green colouring matter. Manures and the principles of manuring From Chemistry of Plant Products:— "D'Arbamont concludes that starch, and presumably also sugar, may or may not be essential for the formation of chlorophyll." Punch, or the London Charivari, Vol. 147, August 26th, 1914 Nearly all bacteria, owing to the absence of chlorophyll, are saprophytic or parasitic forms. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" The several chlorophyll derivatives are further distinguished by characteristic differences in their absorption spectra. The Chemistry of Plant Life But if all plants should die, all animals would die also, for animals cannot make food out of carbon dioxid and water, as they do not have the chlorophyll that puts these things together. Common Science The keels and ribs covering the under-side increased in size and strength, and finally the great leaf was ironed out by the warm sun into a mighty sheet of smooth, emerald chlorophyll. Edge of the Jungle Rather than being transmitted from soils to plant, their functions may consist of the formation of enzymes, proteins, hormones, chlorophyll, antibodies, vitamins, in carbon assimilation. Northern Nut Growers Association Report of the Proceedings at the Thirty-Seventh Annual Report Wooster, Ohio, September 3, 4, 5, 1946 Most of them are colourless, but a few secrete colouring matters other than chlorophyll. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" The chlorophylls will now be in the lower dilute alcohol layer, and the carotinoids in the upper ether, and may be separated by draining of each layer separately. The Chemistry of Plant Life Nothing in the world can put carbon dioxid and water together and make food out of them except certain bacteria and the chlorophyll of plants. Common Science With my electric flash I went out into the starlight, and found the usual hosts struggling nestward with their chlorophyll burdens, and rushing frantically out into the black jungle for more and yet more leaves. Edge of the Jungle In the fourth place it provides a translucent covering, which allows action by the actinic rays of light, which brings the chlorophyll into activity. Northern Nut Growers Association Report of the Proceedings at the Fourteenth Annual Meeting Washington D.C. September 26, 27 and 28 1923 Another solution envisaged shutting off all light from the grass by means of innumerable radiobeams to interrupt the sun's rays in the hope that with an inability to manufacture chlorophyll an atrophy would set in. Greener Than You Think The synthesis of proteins in plants is not a process of photosynthesis, as it can take place in the dark and in the absence of chlorophyll, or any other energy-absorbing pigment. The Chemistry of Plant Life Albinism.—This change is due to the deficient formation of green colouring matter or chlorophyll, and is more a pathological condition than a deformity. Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants We were content to visit him now and then, to arouse him, and then leave him to disincarnate his vertebral outward phase into chlorophyll or lifeless stone. Edge of the Jungle All plant growth is conducted under the influence of chlorophyll, and the actinic rays of light activate this. Northern Nut Growers Association Report of the Proceedings at the Fourteenth Annual Meeting Washington D.C. September 26, 27 and 28 1923 For this purpose a vegetable colouring matter is preferable, and chlorophyll is very suitable. The Handbook of Soap Manufacture It has been shown that these pigments of deep-sea plants are additional to, and not substitutes for, the chlorophylls, etc. The Chemistry of Plant Life In the former case chlorophyll seems never to be formed in the affected parts, even if they be exposed to light, while an etiolated organ, when placed under favorable circumstances, speedily assumes a green colour. Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants There is a marked difference between the functions of the chlorophyll bodies found in plants and the chromatophores found in animals. The Dawn of Reason or, Mental Traits in the Lower Animals Suffice it to say that they are colorless capillary tubes originating in various cells; projecting like the hairs of a brush, containing living protoplasm and evanescent chlorophyll. At the Deathbed of Darwinism A Series of Papers While low in nutrients, it is high in dietetic value, because of the chlorophyll which it contains. Human Foods and Their Nutritive Value If the formaldehyde is not used up rapidly enough by the protoplasm, it kills the enzyme and the undecomposed hydrogen peroxide destroys the chlorophyll, which stops the whole photosynthetic process. The Chemistry of Plant Life The crystals are alive; the opaque faces are lichens that have something like chlorophyll and can make their food from air and sunlight. The Colors of Space And we solemnly begin to prate about chlorophyll. Fantasia of the Unconscious Scientifically, you know green in leaves is owing to 'chlorophyll,' or, in English, to 'greenleaf.' Proserpina, Volume 1 Studies Of Wayside Flowers It has been suggested that it is valuable, too, for supplying iron in an organic form, as there is iron chemically combined with the chlorophyll. Human Foods and Their Nutritive Value Since it is manufactured in the absence of chlorophyll, its formation must be accomplished by some other means than photosynthesis, yet it is composed wholly of glucose—a natural photosynthetic product. The Chemistry of Plant Life Typical plants have chlorophyll; they are able to feed at a low chemical level on air, water, and salts, using the energy of the sunlight in their photosynthesis. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told If now the water containing the blue pigment is filtered, and the residue treated with alcohol, the latter will extract the chlorophyll, becoming colored of a yellow-green. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses The plant is composed throughout of very similar living cells, the more superficial ones containing numerous chlorophyll grains, while starch is stored in the internal cells of the midrib. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" Chemically, the Apple is composed of vegetable fibre, albumen, sugar, gum, chlorophyll, malic acid, gallic acid, lime, and much water. Herbal Simples Approved for Modern Uses of Cure With respect to their colors, the plant pigments may be grouped as follows: Green—the chlorophylls. The Chemistry of Plant Life These cells do not contain either starch or the green coloring-matter, called chlorophyll, which exists in other plants. Among the Mushrooms A Guide For Beginners Careful examination shows that the chlorophyll is confined to several roundish bodies that are not usually in immediate contact with the wall of the cell. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses The dorsiventral thallus is constructed on the same plan throughout the group, and shows a lower region composed of cells containing little chlorophyll and an upper stratum specialized for assimilation and transpiration. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" Chlorophyll makes the plant, and the plant makes chlorophyll. The Breath of Life It is now known, however, that chlorophyll contains neither choline nor phosphorus, the earlier observations being due to mixtures of various other materials with the true chlorophyll in the extracts which were examined. The Chemistry of Plant Life A plant that has no chlorophyll, and obtains its nourishment from dead or living organic matter. Among the Mushrooms A Guide For Beginners Unlike the antheridium, the oögonia contain a great deal of chlorophyll, appearing deep green. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses The wall of the capsule is several layers of cells thick, and since the epidermis contains functional stomata and the underlying cells possess chlorophyll it is capable of assimilation. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" The body struggles to digest and assimilate the food; the chlorophyll in the leaf struggles to store up the solar energy. The Breath of Life Amorphous and Crystalline Chlorophyll.—When the chlorophyll of plants is extracted by alcohol and the alcoholic extract evaporated nearly to dryness, beautiful dark green crystals are obtained. The Chemistry of Plant Life This use of radiant energy occurs only in those parts of the plant in which chlorophyll is present, that is, in the leaves and stems. Artificial Light Its Influence upon Civilization These are fungi consisting of long, undivided, often branching tubular filaments, resembling quite closely those of Vaucheria or other Siphoneæ, but always destitute of any trace of chlorophyll. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses A filamentous protonema is first developed, some of the branches of which are exposed to the light and contain abundant chlorophyll, while others penetrate the substratum as brown or colourless rhizoids. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" The chlorophyll of the leaves and the hemoglobin of the blood are similar in constitution. Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries As has been mentioned, chlorophyll a differs from chlorophyll b by having one more oxygen and two less hydrogen atoms in the molecule, and in having one of its nitrogen atoms in the "lactam" arrangement. The Chemistry of Plant Life There is a large number of reactions due to light in organic chemistry and one of fundamental importance to mankind is the effect of light on the chlorophyll, the green coloring matter in vegetation. Artificial Light Its Influence upon Civilization The Bryophytes, or mosses, are for the most part land plants, though a few are aquatic, and with very few exceptions are richly supplied with chlorophyll. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses In this moss the filamentous protonema is capable of assimilation, but the leaves of the small plants are destitute of chlorophyll, so that they are dependent on the protonema. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" A green pigment, chlorophyll, in the leaf is the medium by which, with the aid of sunlight, the sugars are manufactured. Studies of Trees Actinically, it is a complementary pigment to chlorophyll, that is, it absorbs the blue and green rays and permits the passage of light which is of the wave length that is absorbed by chlorophyll. The Chemistry of Plant Life It can scarcely be expected that these lowly organised plants, differing so much in their manner of growth from the green or chlorophyll bearing plants, can be particularly nourishing. The Chemistry of Food and Nutrition In choosing spores for germination it is best to select those of large size and containing abundant chlorophyll, as they germinate more readily. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses The green colour of the foliage of leafy plants is due to the existence of a substance called chlorophyll, which is almost universally developed in the leaves under the action of light. Darwinism (1889) The chlorophyll gives the leaf its green color, and this explains why a tree pales when it is in a dying condition or when its life processes are interfered with. Studies of Trees The chlorophylls are, of course, the regulator of photosynthesis, absorbing solar energy with which the photosynthetic process may be brought about. The Chemistry of Plant Life So you see it takes light to form this green, or chlorophyll as it is called. The Library of Work and Play: Gardening and Farming. The bulk of the ground tissue is made up of rather large, loose cells, the outer ones containing a good deal of chlorophyll. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses It is a complete organism, protoplastic it may be, with the chlorophyll of age colouring its institutions, but none the less a perfect, living entity. Twenty-One Days in India; and, the Teapot Series Under the action of chlorophyll and sunlight these substances are split up, the carbon, oxygen and hydrogen being combined into plant food. The School Book of Forestry As a rule, they have no chlorophyll, and subsist mainly or wholly on matter already organized, thus utilizing carbon compounds already existing, and not excreting oxygen. The Gutenberg Webster's Unabridged Dictionary Section P and Q The chlorophyll bodies work away on these minerals, and make them into foods. The Library of Work and Play: Gardening and Farming. It is a parasite or saprophyte, and entirely destitute of chlorophyll, being pure white throughout. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses They spelled from the physiology, chlorophyll, coccyx, arytenoid, and the names of the bones and nerves, and all the hard words inside you. Laddie; a true blue story The leaves contain a material known as chlorophyll, which, in the presence of light and heat, changes mineral substances into plant food. The School Book of Forestry The copper combines with the chlorophyll, forming copper phyllocyanate, which, by reason of its insolubility in the gastric juice, is comparatively innocuous. The Project Gutenberg Encyclopedia Volume 1 of 28 If we could hear and see all the work these energetic little chlorophyll bodies are doing, we should be amazed. The Library of Work and Play: Gardening and Farming. They resemble, in their general structure and methods of reproduction, the blue-green slimes, but are, with very few exceptions, destitute of chlorophyll, although often possessing bright pigments,—blue, violet, red, etc. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses The scientific botanist considers how the lilies grow, and can tell all about cells and chlorophyll and the like. Expositions of Holy Scripture St. Luke The energy we obtain from coal or oil is solar energy trapped by the chlorophyll in plant life millions of years ago. Autobiography of a Yogi Thus, when a strong light is viewed through a solution of chlorophyll, the light seen is a brilliant green if the thickness is small, but a deep blood-red for thicker layers. The Project Gutenberg Encyclopedia Volume 1 of 28 This one, called the earth-measurer, has drunk himself green with chlorophyll so as to escape detection. Birds in Town and Village All of them possess chlorophyll, which, however, in many forms, is hidden by the presence of a brown or red pigment. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses And even this latency is not a complete one, as little scales remind us of the leaves, and traces of chlorophyll still exist in the tissues. Species and Varieties, Their Origin by Mutation On the other hand, those plants, such as the fungi, which contain no chlorophyll and are not green, are always, so far as respiration is concerned, in the exact position of animals. Discourses Biological and Geological Essays The effect is complicated, in the case of chlorophyll and many other bodies, by selective reflexion and fluorescence. The Project Gutenberg Encyclopedia Volume 1 of 28 Yes, easily, and some of its contents through the cell's transparent walls, as, for instance, the minute grains of chlorophyll, that is, the green of leaves. Nature's Serial Story These are much smaller than the egg cell, and resemble the zoöspores in form, but are much smaller, and without chlorophyll. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses All plants, moreover, have the power of dissolving albuminous or proteid substances, such as protoplasm, chlorophyll, gluten, aleurone, and of carrying them from one part to other parts of their tissues. Insectivorous Plants Its greenness is due to its chlorophyll, and it undoubtedly has the manufacturing power in full degree, decomposing carbonic acid and setting oxygen free, under the influence of sunlight. Discourses Biological and Geological Essays The conical protuberance, which originally formed the crown of the arch, is now seated on one side, and appears like a joint or knee, which from acquiring chlorophyll becomes green, and increases in size. The Power of Movement in Plants The absence of the chlorophyll has forced them to adopt new relations to food, and compels them to feed upon complex foods instead of the simple ones, which form the food of green plants. The Story of Germ Life The cell is seen in optical section, and the chlorophyll bands are omitted, n, nʹ, the two nuclei. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses In the leaf itself, however, the grains of chlorophyll near the cut surfaces had run together, or become aggregated. Insectivorous Plants The latter contains cellulose, as in ordinary plants; and the chlorophyll which gives the green colour enables the Chlamydomonas to decompose carbonic acid and fix carbon as they do. Discourses Biological and Geological Essays Pringsheim has recently observed under the microscope the destruction of chlorophyll in a few minutes by the action of concentrated light from the sun, in the presence of oxygen. The Power of Movement in Plants But the absence of chlorophyll and the resulting peculiar life has brought about a curious anomaly. The Story of Germ Life This extracts the chlorophyll, but a microscopic examination of the decolored cells shows that the bands remain unchanged, except for the absence of color. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses Nor does chlorophyll seem affected by the intestinal secretions of various animals, judging by the colour of their excrement. Insectivorous Plants The great majority of conspicuous plants are, as everybody knows, green; and this arises from the abundance of their chlorophyll. Discourses Biological and Geological Essays See, also, Stahl on the protection of chlorophyll from intense light, in 'Bot. The Power of Movement in Plants It is their absence of chlorophyll and their consequent dependence upon complex foods which has produced this anomaly. The Story of Germ Life The chlorophyll bands, although much crowded, are at first distinguishable, but later lose the chlorophyll, and become unrecognizable. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses Some soluble matter, however, was extracted from the mucin, pepsin, and chlorophyll, used by me, both by the secretion and by artificial gastric juice. Insectivorous Plants It contains large amounts of highly-assimilable protein due to it's high chlorophyll content, as well as a large amount of beta carotene. How and When to Be Your Own Doctor It is coloured green from its cells containing chlorophyll; and it is seated nearly in the middle of the petiole, instead of at the upper end as in all the other species. The Power of Movement in Plants This is due to the absence of chlorophyll, the green colouring matter of plants, which can only be developed by the presence of light. The Art of Living in Australia ; together with three hundred Australian cookery recipes and accessory kitchen information by Mrs. H. Wicken This pigment is found in the chlorophyll bodies, and usually quite conceals the chlorophyll, which, however, becomes evident so soon as the red pigment is removed. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses It must not be supposed from these facts that the grains of chlorophyll, as they exist in living plants, cannot be attacked by the secretion; for these grains consist of protoplasm merely coloured by chlorophyll. Insectivorous Plants Spring grass, growing in the most intense sunlight of the year contains very high levels of chlorophyll and vitamins. How and When to Be Your Own Doctor It consists of a mass of small cells usually of a pale colour from the absence of chlorophyll, and with its outline more or less convex, as shown in the annexed figure. The Power of Movement in Plants These salts give the green color to the chlorophyll in leaves and grass, and bottle glass owes its green color to ferrous silicate. An Introduction to Chemical Science On carefully removing a bit of the younger growth and examining it microscopically, it is found to consist of long filaments much like those of Vaucheria, but entirely destitute of chlorophyll.

Insectivorous Plants I am investigating the action of carbonate of ammonia on chlorophyll, which makes me want the plants in my list. More Letters of Charles Darwin — Volume 2 The cells with chlorophyll next lose more or less completely their green colour, and their contents finally become brown. The formation of vegetable mould through the action of worms, with observations on their habits While this chemical action is of the utmost importance for organisms, the nutrition of which depends upon the action of chlorophyll, it becomes of less importance for organisms devoid of chlorophyll. Darwin and Modern Science The outer cells of the ground tissue in the green branches contain chlorophyll, and the walls of some of them are thickened.
