When that reflected light enters your eyes, you perceive plants as green. If they are photosynthetic, they use the light energy from the sun to produce food in the form of glucose. 2. When pigments are extracted, the antenna complexes, reaction centers, and ETCs have been disassembled, so the energy is given off as fluorescence and/or heat. Chlorophyll is green - so absorbs the red and blue parts of the electromagnetic spectrum and reflects the green part of the spectrum. During the fall, many plants lose their chlorophyll, and the other colored pigments of the leaf are seen. What is the role of chlorophyll in photosynthesis?
