definition: Chlorophyll is a green substance that exists in the leaves and stems of plants. Chlorophyll is very important because it makes it possible for plants to produce food for themselves using sunlight.
Almost all plants have chlorophyll, but a few don't. Without chlorophyll these plants can't make their own food. They have to get it through other plants or fungi.
derivation: chlorophylloid (adj.)
