Biology for AP Courses 2022-06-09T00:00:00Z The researchers added a fluorescent label to the snoRNAs and found that, rather than staying in the nucleus as previously thought, they were located in the cytoplasm. (Cellular) Death by Chocolate 2011-07-05T18:11:34Z Increase in size following emergence from hibernation may be due in part to proliferation of the sustentacular cytoplasm. Natural History of the Ornate Box Turtle, Terrapene ornata ornata Agassiz 2011-10-01T02:00:30.200Z A young trophozoite which is becoming a gametocyte is distinguished from one which gives rise to a schizont by its much slower rate of growth, and the absence of any vacuoles in its cytoplasm.

Circadian clock without DNA--History and the power of metaphor 2011-02-11T16:15:02.303Z "Frankincense separates the 'brain' of the cancerous cell - the nucleus - from the 'body' - the cytoplasm, and closes down the nucleus to stop it reproducing corrupted DNA codes." 2010-02-09T10:59:00Z It can develop vacuoles, or rather fine bubbles of carbonic acid gas in its cytoplasm, to float up to the surface of the water. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 4 "Aram, Eugene" to "Arcueil" If in the cytoplasm of a cell there are two points of molecular concentration greater than that of the general mass, the nucleus must necessarily divide with all the phenomena which accompany karyokinesis. The Mechanism of Life Translation of RNA to protein occurs in the cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z All the stuff that is happening in the cytoplasm is referred to as "post-translational" as if it was just something more that DNA "caused", perhaps a little further downstream than usual. Circadian clock without DNA--History and the power of metaphor 2011-02-11T16:15:02.303Z The condensation of amino-acids into proteins, or the reverse decomposition, is very readily accomplished in all living protoplasm, under the influence of special protein-attacking enzymes, which are almost universally present in the cytoplasm. The Chemistry of Plant Life The nucleus of each spore next divides, again directly, and this is followed by the division of the cytoplasm. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 5 "Clervaux" to "Cockade" Thus the cell becomes organized, forming its own cytoplasm and its own enveloping membrane.

Biology for AP Courses 2022-06-09T00:00:00Z Floating in the cytoplasm may be found a tiny body known as the Centrosome, which acts as a magnet in certain phases of cell development. The Eugenic Marriage, Volume I. (of IV.) A Personal Guide to the New Science of Better Living and Better Babies Development is thus due in part to a qualitative division not of the nucleus but of the cytoplasm. Form and Function A Contribution to the History of Animal Morphology Surrounding and inclosing the cytoplasm, in many cells, is a thin outer layer, or membrane, which affords more or less protection to the contents of the cell. Physiology and Hygiene for Secondary Schools We may in this way obtain endless varieties, nuclei which are opaque or transparent, with or without a nucleolus, and cells containing homogeneous cytoplasm without a nucleus. The Mechanism of Life RNA is created and spliced in the nucleus, but needs to be transported to the cytoplasm to be translated.

Physiology and Hygiene for Secondary Schools We may also obtain cells with cytoplasm filling the whole of the cellular cavity or separated from the cell-membrane. The Mechanism of Life RNA is transported to the cytoplasm through the nuclear pore complex. Biology for AP Courses 2022-06-09T00:00:00Z The mass outside of the nucleus is termed "cytoplasm," and this may be homogeneous in appearance or may contain granules. Disease and Its Causes This disrupts the chemical bonds for critically important cell structures like the cytoplasm, which carries the cell's genetic blueprints, and also produces chemical constituents which can cause as much damage as the original ionizing radiation. Worldwide Effects of Nuclear War: Some Perspectives The nuclei multiplied by segmentation migrate into the superficial cytoplasm surrounding the yolk, and then this cytoplasm segments, and each part of the cytoplasm develops into a particular region of the embryo. Hormones and Heredity Organization -- N. organized world, organized nature; living nature, animated nature; living beings; organic remains, fossils. protoplasm, cytoplasm, protein; albumen; structure &c. Roget's Thesaurus of English Words and Phrases The RNA stability can be increased, leading to longer residency time in the cytoplasm, or decreased, leading to shortened time and less protein synthesis. Biology for AP Courses 2022-06-09T00:00:00Z The general mass of material forming the cell is termed cytoplasm. Disease and Its Causes The earliest process of inorganic differentiation in the structureless body of the Monera led to its division into two different substances—the caryoplasm and the cytoplasm. The Evolution of Man — Volume 2 The nucleus, and especially the chromosomes, are supposed in some unknown way to influence or govern the metabolism of the cytoplasm. Hormones and Heredity Compared with the method of division of the nucleus, that of the cytoplasm appears to be very simple. Darwin and Modern Science Because lipid hormones can diffuse across cell membranes, their receptors are located in the cytoplasm of target cells. Biology for AP Courses 2022-06-09T00:00:00Z On the outside is a cell membrane which encloses cytoplasm and nucleus; the latter, however, is not in a single mass, but the nuclear material is distributed through the cell. Disease and Its Causes The cytoplasm is the outer and softer part, the substance of the body of the cell. The Evolution of Man — Volume 2 It may be supposed that as there was only the cytoplasm of one ovum, each nucleus would determine the characters of half the individual developed. Hormones and Heredity The cytoplasm of the male sexual cell is therefore not necessary to ensure a transference of hereditary characters from parents to offspring. Darwin and Modern Science The steroid hormones pass through the plasma membrane of a target cell and adhere to intracellular receptors residing in the cytoplasm or in the nucleus.

Biology for AP Courses 2022-06-09T00:00:00Z These cells grow vigorously and their cytoplasm increases, their growth being accompanied by a correspondingly direct multiplication of the nuclei. Darwin and Modern Science The specific response of a cell to a lipid insoluble hormone depends on the type of receptors that are present on the cell membrane and the substrate molecules present in the cell cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm’s density will inhibit the movement of the materials. Biology for AP Courses 2022-06-09T00:00:00Z In fact, the cytoplasm in plants is always slightly hypertonic to the cellular environment, and water will always enter a cell if water is available. Biology for AP Courses 2022-06-09T00:00:00Z However, the cell membrane detaches from the wall and constricts the cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z In the developing eggs of insects the nuclei, together with some cytoplasm, migrate to the periphery of the egg. Darwin and Modern Science These enzymes are active at a much lower pH than that of the cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z The carrier protein, in its new configuration, has a decreased affinity for potassium, and the two ions are released into the cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z It will remain facing the cytoplasm, but no sodium ions would bind. Biology for AP Courses 2022-06-09T00:00:00Z Photosynthesis absorbs light energy to build carbohydrates in chloroplasts, and aerobic cellular respiration releases energy by using oxygen to metabolize carbohydrates in the cytoplasm and mitochondria. Biology for AP Courses 2022-06-09T00:00:00Z These molecules help to spread a signal through the cytoplasm by altering the behavior of certain cellular proteins. Biology for AP Courses 2022-06-09T00:00:00Z Therefore, the pH within lysosomes is more acidic than the pH of the cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z Internal receptors are found in the cell cytoplasm.

Biology for AP Courses 2022-06-09T00:00:00Z Like prokaryotes, all eukaryotic cells have a plasma membrane, cytoplasm, ribosomes, and DNA. Biology for AP Courses 2022-06-09T00:00:00Z Many reactions that take place in the cytoplasm could not occur at a low pH, so again, the advantage of compartmentalizing the eukaryotic cell into organelles is apparent. Biology for AP Courses 2022-06-09T00:00:00Z Functional ribosomes are found either free in the cytoplasm or attached to the rough endoplasmic reticulum where they perform protein synthesis. Biology for AP Courses 2022-06-09T00:00:00Z Even though the cytoplasm consists of 70 to 80 percent water, it has a semi-solid consistency, which comes from the proteins within it. Biology for AP Courses 2022-06-09T00:00:00Z Ions of sodium, potassium, calcium, and many other elements are also dissolved in the cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z The nuclear envelope is punctuated with pores that control the passage of ions, molecules, and RNA between the nucleoplasm and cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z Ribosomes are either found in the cytoplasm or attached to the cytoplasmic side of the plasma membrane or endoplasmic reticulum. Biology for AP Courses 2022-06-09T00:00:00Z That’s because as the water concentration in the soil becomes lower than the water concentration in the plant, water moves out of the central vacuoles and cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z When the central vacuole holds more water, the cell gets larger without having to invest a lot of energy in synthesizing new cytoplasm. Biology for AP Courses 2022-06-09T00:00:00Z In the nucleus, DNA is used to make RNA which exits the nucleus and enters the cytoplasm of the cell. Biology for AP Courses 2022-06-09T00:00:00Z Plant cells and animal cells both have a rigid plasma membrane as well as cytoplasm which is the gel-like solution that fills the cell.
