Question

plants carry out both photosynthesis and cellular respiration. which statement best compares the way these two processes handle energy?
a
photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration releases that stored energy to produce atp for cellular work.
b
photosynthesis releases energy from glucose molecules to create atp, while cellular respiration stores light energy in the bonds of glucose.
c
photosynthesis captures energy directly into atp for long - term storage, while cellular respiration breaks down water molecules to release atp.
d
photosynthesis captures heat energy from sunlight to warm plant tissues, while cellular respiration stores that heat energy in chemical bonds.

Explanation:

To solve this, we analyze each option:

• Option A: Photosynthesis uses light energy to make glucose (storing chemical energy), and cellular respiration breaks down glucose to produce ATP (using stored energy for work). This matches the energy flow of both processes.
• Option B: Photosynthesis stores energy in glucose, cellular respiration releases it. So this is reversed.
• Option C: Photosynthesis produces glucose (long - term energy storage), not directly ATP for long - term. Cellular respiration breaks down glucose (not water) for ATP.
• Option D: Photosynthesis captures light energy for chemical storage (in glucose), not to warm tissues. Cellular respiration releases energy (some as heat), not store heat energy in bonds.

Answer:

A. Photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration releases that stored energy to produce ATP for cellular work.
