I am sure that you have heard about Chlorophyll, which is a molecule , a pigment presented in very high quantities in plants in chloroplasts and is what makes them green. Well it is green because it absorbes light strongly in the blue and red area of the elextromagnetic spectrum ( sun light is a composition of various wavelenghts - colors) and what remains and reflected is green. The energy from the light absorbed is then transformed to electrical and then to chemical energy.
