It is a pigment that absorbs light energy and aids in the photosynthesis. Chlorophyll exists in many forms, such as chlorophyll a, chlorophyll b, etc. The chlorophyll absorbs light energy of red and blue wavelengths. Whereas, the green light is not absorbed and is reflected back.

WebChlorophyll A and B. For a majority of organisms capable of photosynthesis (plants, cyanobacteria, algae) chlorophyll a is the primary pigment of photosynthesis. It's responsible for absorbing light in the orange to red and violet to blue spectrum that provides the energy required for subsequent photosynthetic reactions.
