Which of the following is not a difference between photosynthesis and cellular respiration?
A. Where they occur in cells
B. Being part of the carbon cycle
C. The products of the processes
D. The materials needed for the processes

Explanation:

Photosynthesis and cellular respiration are both important processes to utilize energy and maintain life in an organism. There are many differences between the two, but we are asked to identify the answer that is not a difference.

A. Where they occur in cells

Photosynthesis occurs in chloroplasts in plants, algae, and some bacteria. Cellular respiration occurs in mitochondria in all organisms. This is a difference.

B. Part of the carbon cycle

The carbon cycle describes the exchange and movement of carbon throughout the Earth, atmosphere, and biosphere. Photosynthesis uses carbon dioxide and cellular respiration produces it, so they are both part of the carbon cycle. This is not a difference. This seems to be correct, but let's check the other choices.

C. The products of the processes

Photosynthesis produces oxygen and glucose, while cellular respiration makes carbon dioxide, water, and energy or ATP.

D. The materials needed for the processes

Photosynthesis needs carbon dioxide, water, and energy from the sun, while cellular respiration needs oxygen and glucose.

Both photosynthesis and cellular respiration are part of the carbon cycle, so the choice that is not a difference is Choice B.
