Photosynthesis (IMAGE) NASA/Goddard Space Flight Center Caption In the process of photosynthesis, plants convert energy from the sun into chemical energy in the form of glucose, or sugar. The chlorophyll in plants absorbs more blue and red light from sunlight, and less green light. Chlorophyll is green, because it reflects green light more than blue and red light.
