Chlorophyll (also chlorophyl) is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants.[2] Its name is derived from the Greek words χλωρός, khloros ("pale green") and φύλλον, phyllon ("leaf").[3] Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light.
