What is an photosynthesis? Explain ur answer

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

The process of plant cells using water, carbon dioxide and sunlight energy to make glucose (sugar) and oxygen. And the process in processed in the chloroplast, and inside the chloroplast is a green pigment called the chlorophyll that traps sunlight energy and generate oxygen.
