Oil spill imperils an unseen world at the bottom of the gulf 2010-05-16T04:00:00Z The bacteria on the right side, R. Palustris, are photosynthetic, converting sunlight into sugar, which they need to survive. 2010-02-12T18:54:00Z The whole photosynthetic process takes place in chlorophyll-containing plant tissues with astonishing rapidity, sugars, and even starch, appearing in the tissues almost immediately after their exposure to light in the presence of carbon dioxide. The Chemistry of Plant Life The sweetish, starchy liquid that they could suck through a tube from the air-restorers—it was a by-product of the photosynthetic process—might even have sustained them for a considerable interval. The Planet Strappers These short-term effects alone-intense cold, darkness, and acid rain and snow-kill the plants and photosynthetic plankton, the base of most food chains. The Runaway Asteroid 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 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 Their close association with the photosynthetic carbohydrates has led many investigators to seek to establish for them some significant function as food materials, or as plastic substances in cell metabolism. The Chemistry of Plant Life The internal lights of their air-restorers could be used again, augmenting the action of the pale sunshine on the photosynthetic processes of the chlorophane. The Planet Strappers It is produced in large quantities in green leaves as the temporary storage form of photosynthetic products. The Chemistry of Plant Life It may be, therefore, that tannins serve as safety accumulations of excessive condensations of formaldehyde, or other photosynthetic products, under such conditions. The Chemistry of Plant Life 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 Assuming, then, that formaldehyde is the first photosynthetic product in the process of the production of carbohydrates from water and carbon dioxide, the simple empirical equation for this transformation would be H2O + CO2 = CH2O + O2.
