The correct response that summarizes the relationship between photosynthesis and cellular respiration is:
The products of photosynthesis are the reactants of cellular respiration.
Photosynthesis, which occurs in plants, converts carbon dioxide and water into glucose and oxygen using sunlight. The glucose and oxygen produced during photosynthesis are then used in cellular respiration, which takes place in both plants and animals, to generate energy in the form of ATP, carbon dioxide, and water. This cyclical relationship highlights how these two processes are interconnected, with photosynthesis providing the necessary components for cellular respiration, while cellular respiration produces byproducts that are utilized in photosynthesis.
