Question

1. which statement best connects photosynthesis and cellular respiration?

a. both occur in chloroplasts
b. photosynthesis makes glucose used in respiration
c. respiration produces sunlight
d. both store energy in oxygen

Explanation:

• Option A: Cellular respiration occurs in mitochondria (and cytoplasm), not chloroplasts, so A is incorrect.
• Option B: Photosynthesis produces glucose (and oxygen) using light energy, and cellular respiration breaks down glucose to release energy, so photosynthesis makes glucose used in respiration. This is correct.
• Option C: Respiration does not produce sunlight; sunlight is used in photosynthesis, so C is incorrect.
• Option D: Photosynthesis releases oxygen and stores energy in glucose, while respiration uses oxygen and releases energy from glucose. They don't store energy in oxygen, so D is incorrect.

Answer:

B. Photosynthesis makes glucose used in respiration
