answer:Photosynthesis is the process by which green plants and other organisms transform light energy into chemical energy in the form of glucose. Carbon dioxide and water are absorbed through the leaves of the plant and exposed to sunlight. Chlorophyll, a pigment found in plants, absorbs the sunlight and uses the energy to convert carbon dioxide and water into glucose and oxygen gas. The glucose produced during photosynthesis is used by the plant as a source of energy for growth and metabolism, while the oxygen is released into the atmosphere as a byproduct.
