Question

Why can photosynthesis and cell respiration be considered opposite processes?

a) Photosynthesis removes carbon dioxide from the atmosphere, and cell respiration puts it back.
b) Photosynthesis removes oxygen from the atmosphere, and cell respiration puts it back.
c) All of the above are true statements.
d) Photosynthesis releases energy, and cell respiration stores energy.

Answer 1

Therefore, the correct answer is c) All of the above are true statements.
Photosynthesis removes carbon dioxide from the atmosphere, and cell respiration puts it back. Photosynthesis removes oxygen from the atmosphere, and cell respiration puts it back. Photosynthesis releases energy, and cell respiration stores energy.

Step-by-step explanation:

Photosynthesis and cellular respiration can be considered opposite processes because they have opposite effects on the levels of carbon dioxide and oxygen in the atmosphere. Photosynthesis removes carbon dioxide from the atmosphere, while cellular respiration puts it back. Similarly, photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it back, making option a) also true. Additionally, photosynthesis releases energy, while cellular respiration stores energy, making option d) true as well.
