Question

In Units 4A and 4B, we have learned about photosynthesis and cellular respiration. Which of the following statements is true?
a. The reactants of photosynthesis are the reactants of cellular respiration.
b. Photosynthesis produces light energy while cellular respiration produces chemical energy.
c. The products of photosynthesis are the reactants of cellular respiration.
d. Photosynthesis and cellular respiration use light energy to convert to chemical energy.

Answer 1

Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
