Explanation:
Chlorophyll is a pigment that absorbs electromagnetic radiation of the visible spectrum that is used in process of photosynthesis. Chlorophyll's function is to absorb electromagnetic radiation of the visible spectrum and it absorbs blue color radiation the best and green the worst as it reflects it. It absorbs electromagnetic radiation by absorbing the energy of the photon of light by a process called charge separation.
Charge separation is the process by which an electron gets to a higher energy state by absorbing the energy of a photon.
