 (klôr′ə-fĭl)
n.
Any of a group of green pigments that capture light energy used as the energy source in photosynthesis and that are found in the chloroplasts of plants and other photosynthetic organisms such as cyanobacteria, especially:
a. A waxy blue-black microcrystalline green-plant pigment, C55H72MgN4O5, with a characteristic blue-green alcohol solution. Also called chlorophyll a.
b. A similar green-plant pigment, C55H70MgN4O6, having a brilliant green alcohol solution. Also called chlorophyll b.

(klôr′ə-fĭl)
Any of several green pigments found in photosynthetic organisms, such as green plants. Chlorophyll is composed of carbon, hydrogen, magnesium, nitrogen, and oxygen. See more at photosynthesis.
Word History From its name, we might think that chlorophyll has chlorine in it, but it doesn't. The chloro- of chlorophyll means "green"; chlorophyll in fact is the chemical compound that gives green plants their characteristic color. The name of the chemical element chlorine comes from the same root as the prefix chloro-, and is so called because it is a greenish-colored gas.

chlorophyll

A green pigment that “traps” sunlight for photosynthesis; found in plants and some protists.
