Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In angiosperms, this chemical reaction is light-dependent. Green plants have the ability to make their own food. Using the energy of light, carbohydrates such as sugars are synthesised from carbon dioxide and water. C. It reflects all colors in the light spectrum except green. When pigments are extracted, the antenna complexes, reaction centers, and ETCs have been disassembled, so the energy is given off as fluorescence and/or heat. 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. 11. The sunlight is absorbed by the chlorophyll in the leaves of the plants. Chloroplast Functions Chloroplasts carry out the process of photosynthesis. The ATP molecule is the basic source of energy in all living cells. It is a waste product and is released into the atmosphere.
