Full Answer

Through the photosynthesis process, sunlight is used to convert carbon dioxide and water into a carbohydrate (glucose) and oxygen. The process involves the conversion of solar energy to chemical energy. The production of glucose aids in the growth of plant cells.

Photosynthesis occurs in the chloroplasts of plant leaves that absorb the sunlight. However, there are many other plant cell structures, such as cytoplasm and chlorophyll, that also are necessary for the photosynthesis process.
