Question

which statement correctly describes how photosynthesis and cellular respiration are related?
a. the energy captured during photosynthesis is then used by organisms for cellular respiration.

b. earths sun directly provides the energy required for photosynthesis and cellular respiration.

c. the energy released during cellular respiration provides the energy needed for photosynthesis.

d. the organelle that captures energy for photosynthesis releases energy for cellular respiration.

Explanation:

• Option A: Photosynthesis captures energy (in glucose) which is then used in cellular respiration to release energy for organisms. This is correct.
• Option B: The sun provides energy for photosynthesis directly, but cellular respiration uses energy from glucose (produced via photosynthesis), not direct solar energy. So B is wrong.
• Option C: Photosynthesis requires energy from the sun, while cellular respiration releases energy from glucose. The energy for photosynthesis doesn't come from cellular respiration. So C is wrong.
• Option D: Chloroplasts capture energy for photosynthesis, and mitochondria release energy for cellular respiration. Different organelles, so D is wrong.

Answer:

A. The energy captured during photosynthesis is then used by organisms for cellular respiration.
