The carbon cycle is not only replenished by photosynthesis, but it also produces oxygen to sustain life. A. The presence of chlorophyll is necessary for photosynthesis because it absorbs light energy and transports it to two different types of storage molecules. In which reaction is each used? In plants, chlorophyll surrounds photosystems in the thylakoid membrane of organelles called chloroplasts, which are concentrated in the leaves of plants. Explain what happens when sunlight hits chlorophyll molecules. The importance of pigment in photosynthesis is that it helps absorb the energy from light. During the fall, many plants lose their chlorophyll, and the other colored pigments of the leaf are seen. 2. This cookie is set by GDPR Cookie Consent plugin.
