Sunlight gives off UV rays, which plants absorb to turn into energy. This energy that plants make is called ATP. In order for photosynthesis to occur, ATP must be present (Photosynthesis is how the plants make food) Because light is all the colors of the Visible Light Spectrum, or Rainbow. All colors EXCEPT green are absorbed in the chlorophyll. Green is the color reflected and transmitted back, and that is why we see green in plants.
