For substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Describe what happens to these four substances during photosynthesis. Write your response below

Carbon dioxide and water enter the plant while sugars and oxygen are released into the atmosphere.
