takes place. Similar chlorophyll granules have been found
in the tissues of the lower animals. [Written also
chlorophyl.]

2. 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

central nitrogens, and has a phytyl side chain. It is
essential for photosynthesis in most plants. {Chlorophyll
