chlo·ro·phyll

(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.
