Role of Chlorophyll in Photosynthesis The overall balanced equation for photosynthesis is: 6 CO 2 + 6 H 2 O C 6 H 12 O 6 + 6 O 2 where carbon dioxide and water react to produce glucose and oxygen. Photosynthesis is responsible for the production of oxygen in the atmosphere, as well as many other processes, and it is essential for the survival of many plants and animals. C. Colorless a. Chlorophyll B's role is to give organisms the ability to absorb higher frequency blue light for use in photosynthesis. Phytoplankton, the microscopic floating plants that form the basis of the entire marine food web, contain chlorophyll, which is why high phytoplankton concentrations can make water look green. 6 What is the most important photosynthetic pigment in a plant? A. Chlorophyll is green - so absorbs the red and blue parts of the electromagnetic spectrum and reflects the green part of the spectrum. Yellow NADPH, in turn, is used to reduce carbon dioxide (CO2) into sugars, such as glucose. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. D. The rate of photosynthesis will be greater in bright white light than in darkness. What is the role of water in photosynthesis? There is an intermediate molecule called protochlorophyllide, which is converted into chlorophyll. In plants, chlorophyll surrounds photosystems in the thylakoid membrane of organelles called chloroplasts, which are concentrated in the leaves of plants. The thylakoids are flattened sacs or vesicles. Plants are one of a few organisms on earth that can trap the sun's energy and turn it into high-energy sugars and oxygen: two very important molecules that we couldn't survive without. E.
