Definitions

from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun Any of a group of green pigments that absorb light energy used in photosynthesis and that are found in the chloroplasts of plants and other photosynthetic organisms such as cyanobacteria, especially.
  • noun A waxy blue-black microcrystalline green-plant pigment, C55H72MgN4O5, with a characteristic blue-green alcohol solution.
  • noun A similar green-plant pigment, C55H70MgN4O6, having a brilliant green alcohol solution.

  • noun (Bot.) Literally, leaf green; a green granular matter formed in the cells of the leaves (and other parts exposed to light) of plants, to which they owe their green color, and through which all ordinary assimilation of plant food takes place. Similar chlorophyll granules have been found in the tissues of the lower animals.
  • noun any of a group of green pigments found in photosynthetic organisms. Chlorophyll a and chlorophyll b are found in higher plants and green algae; chlorophyll c is found in certain types of marine algae. Chemically, it has a porphyrin ring with a magnesium ion bound to the four central nitrogens, and has a phytyl side chain. It is essential for photosynthesis in most plants. Chlorophyll a has formula C55H72N4O5Mg.

  • Looks like the "middle ground" is where the quantum mystics hang out and propose unnecessary quantum explanations for well-understood chemical mutation processes based on an extremely vague analogy between photon capture in chlorophyll and base pair mutations in DNA.

  • And the darker leaves on plants are good for you, she explains, because they contain "chlorophyll - the 'blood' of the plant - which will really oxygenate your blood."'
