What IS photosynthesis ?

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.

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.

Carbon dioxide, water and light are all needed for photosynthesis to take place.

A chemical reaction is permanent, cannot be undone.

The photosynthesis almost acts as a fuel to the organism.
