Four 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.
Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
