A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. What is the purpose of the light dependent reaction? It's responsible for absorbing light in the orange to red and violet to blue spectrum that provides the energy required for subsequent photosynthetic reactions. The two main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy. The light energy strikes the leaf, passes into the leaf and hits a chloroplast inside an individual cell. B. Plants and other photosynthetic organisms use chlorophyll to absorb light (usually solar energy) and convert it into chemical energy. Trees are frequently cited as the main source of oxygen for the planet, but this is not the case. Chlorophylls job in a plant is to absorb lightusually sunlight. This oxygen allows many non-plants to undergo respiration as well, thereby supporting life on Earth. Carotenoids are a class of phytonutrients ("plant chemicals") and are found in the cells of a wide variety of plants, algae and bacteria. The carbon dioxide in the water is transformed into glucose, which is a sugar, and the water is transformed into oxygen. Why is water so vitally important in photosynthesis? Carbon dioxide enters the plant through structures called the stomata, which are usually found on the underside of the leaves. 9 molecules of ATP and 6 molecules of NADPH.

Carbon fixation. What is the role of photosynthetic pigments in the process of photosynthesis? The ATP molecule is the basic source of energy in all living cells. This ultimately creates the concentration gradient needed inside the thylakoid to produce ATP. Accessory pigments are pigments that absorb light energy from the sun and transfer the energy to chlorophyll-a molecules during photosynthesis. The chloroplast has different membranes like stroma . An ATP molecule consists of three "parts." NADPH plays a big role in the light-independent reaction when it is used, along with ATP, to produce high energy sugars. Photons can be used to remove carbon dioxide (CO2) and other organic compounds. The Calvin Cycle uses 6 molecules of carbon dioxide to ultimately produce a single 6-carbon sugar molecule. The hydrogen is taken (ETC) to the stroma by NADPH along with the grana's remaining light energy. Chloroplasts play an important part in the process of photosynthesis in some organisms. Why do leaves change color in the autumn? The results can be seen in the table below.
