Question 7

Compare photosynthesis and cellular respiration

Answer 7

photosynthesis converts carbon dioxide and water into oxygen and glucose.

cellular respiration converts oxygen and glucose into water and carbon dioxide.

Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy.

Cellularrespiration :It is the controlled release of energy from organic compounds to produce ATP
