chlorophyll / klɔːrəfɪl /
Množina reči chlorophyll je chlorophylls.
ETYM Greek chloros light green + phyllon leaf: cf. French chlorophylle.
Any of a group of green pigments found in photosynthetic organisms; SYN. chlorophyl.
Green coloring matter of plants.
Green pigment present in most plants; it is responsible for the absorption of light energy during photosynthesis.
The pigment absorbs the red and blue-violet parts of sunlight but reflects the green, thus giving plants their characteristic color.
Chlorophyll is found within chloroplasts, present in large numbers in leaves. Cyanobacteria (blue-green algae) and other photosynthetic bacteria also have chlorophyll, though of a slightly different type. Chlorophyll is similar in structure to hemoglobin, but with magnesium instead of iron as the reactive part of the molecule.
