Chlorophyll is a green agent created by the process of photosynthesis. The word is derived from two Greek words: chloros meaning green, and phyllon meaning leaf.
There are specialized photosynthetic cells in a plant's leaves which convert sunlight into carbohydrates. Carbohydrates are necessary for the transportation of energy throughout the plant's system.
Chlorophyll is found in plants, algae and in cyanobacteria.
