The carbon dioxide in the water is transformed into glucose, which is a sugar, and the water is transformed into oxygen. Chlorophyll, a light-sensitive pigment, is found in many of these membranes. SEE NUMBER 9. 3 What role do pigments like chlorophyll play in photosynthesis? Chlorophyll's electrons absorb the energy from the sun. Through photosynthesis the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose a type of sugar. D. Chloroplasts. 4 What role does the pigment play in the light reactions quizlet? what happens during the light-independent cycle? 6 What is the most important photosynthetic pigment in a plant? Water is also required for photosynthesis. During the fall, many plants lose their chlorophyll, and the other colored pigments of the leaf are seen. In this way ATP synthase binds a phosphate to ADP to form ATP. d) Reduction of leaf surface area as seen in the needles of evergreens. Chlorophyll absorbs certain wavelengths of light and reflects green light. chlorophyll is present in these organelles, allowing them to capture light energy and initiate the chemical reaction. A photosystem is a collection of pigment molecules that serve as the light-collecting unit of photosynthesis.
