<em><u>The main use of chlorophyll for photosynthesis is to capture the electromagnetic light energy from the sun. Sunlight is broken up into a spectrum of colors, the visible portion of which humans see in rainbows and in light shone through prisms. Chlorophyll uses the red and blue parts of the light to create the energy required for photosynthesis. Different forms of chlorophyll absorb slightly different colors of light. No types absorb green light, so all of the green light from the sun is reflected by the plant, which makes humans see them as green in </u></em><em><u>color.</u></em>
