Photosynthesis and Cellular Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are opposite processes; the products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and vice versa.
