Answer:
Photosynthesis is a process used by plants, algae, and some bacteria to convert sunlight into chemical energy. This energy is stored in the form of sugars, which can then be used by the organism for growth and development. During photosynthesis, light energy is absorbed by chlorophyll molecules and converted into chemical energy, which is then used to produce sugars from carbon dioxide and water. Oxygen is also produced as a by-product of the reaction.
