Chlorophyll's job in a plant is to absorb lightusually sunlight. One floats on water; the other sinks. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. From there on, the energy from the sun will ultimately become chemical energy that can be used by the organism for cellular processes. (1) The nitrogen base adenine. Both Chlorophyll A and B have very similar structures. 2. List some adaptations found in leaves that help to reduce water loss. 58. Plants use sunlight to produce oxygen and store chemical energy in glucose as part of photosynthesis. All of them have different absorption spectra, that is, they absorb light at different wavelengths. Why do plants have multiple pigments inside their chloroplasts? The first produces adenosine triphosphate (ATP) and nicotinamide adenine dinucleaotide phosphate hydrogen (NADPH) molecules. Chlorophyll is derived from the Greek words chloros, which mean green and phyllon, which means leaf. Chlorophyll is the most well-known pigment for its role in photosynthesis, but there are many others that play a role. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis. Carbon dioxide enters through the stomata in the leaf. The level of liquid in the volumeter went down because the plant was using up the available carbon dioxide in the water. 11. Does chloroplast capture sunlight energy for photosynthesis? A.
