Which of the following statements accurately describes the relationship between photosynthesis and cellular respiration? The primary function of photosynthesis is to use solar energy to synthesize ATP; the primary function of respiration is to break down ATP to release energy. The process of photosynthesis only occurs in autotrophs, while cellular respiration only occurs in heterotrophs. Photosynthesis uses solar energy to convert inorganics to energy-rich organics; cellular respiration breaks down organics to synthesize ATP. Photosynthesis and cellular respiration occur in separate, specialized organelles, and the two processes cannot occur in the same cell at the same time.

a) The primary function of photosynthesis is to use solar energy to synthesize ATP; the primary function of respiration is to break down ATP to release energy. I think this option describes best the relationship between photosynthesis and cell respiration.

b) The process of photosynthesis only occurs in autotrophs, while cellular respiration only occurs in heterotrophs. Cellular respiration also occurs in plants. So this option is incorrect.

c) Photosynthesis uses solar energy to convert inorganics to energy-rich organics; cellular respiration breaks down organics to synthesize ATP. This option is also posible but is not as complete as the first option.

d) Photosynthesis and cellular respiration occur in separate, specialized organelles, and the two processes cannot occur in the same cell at the same time. Photosynthesis occurs in chloroplasts but both photosynthesis and chloroplasts can occurs in plants.
