Question

1. how are the processes of photosynthesis and cellular respiration interrelated?

a photosynthesis releases energy and cellular respiration stores energy.
b photosynthesis is unique to plants and cellular respiration is unique to animals.
c the products of photosynthesis are carbon dioxide and water; cellular respiration produces oxygen and sugars.
d photosynthesis removes carbon dioxide from the atmosphere and cellular respiration releases carbon dioxide into the atmosphere.

Explanation:

• Option A: Photosynthesis stores energy (in glucose) using light energy, while cellular respiration releases energy (from glucose). So this option is incorrect.
• Option B: Cellular respiration occurs in both plants and animals. Plants carry out cellular respiration (in mitochondria) just like animals. So this option is incorrect.
• Option C: The products of photosynthesis are oxygen and glucose (sugars), and the products of cellular respiration are carbon dioxide and water. So this option is incorrect.
• Option D: Photosynthesis uses carbon dioxide (\(CO_2\)) from the atmosphere (along with water) to make glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide (released to the atmosphere), water, and energy. This shows an inter - relationship in terms of carbon dioxide exchange.

Answer:

D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration releases carbon dioxide into the atmosphere.
