Answer:
During photosynthesis, plants use energy from sunlight to convert carbon dioxide and water into glucose (a sugar) and oxygen. The energy from sunlight is absorbed by pigments in the plant cells called chlorophyll, which are found in the chloroplasts. The energy from the absorbed light is used to split water molecules into hydrogen and oxygen, and the hydrogen is combined with carbon dioxide to form glucose. This process requires a lot of energy, which is provided by the sunlight. In addition to producing glucose, photosynthesis also produces oxygen, which is released into the atmosphere and used by animals and other organisms for respiration. Therefore, photosynthesis is a vital process for the survival of plants and the entire ecosystem, as it provides the energy and oxygen needed for life.
