Under what conditions do photosynthesis and cellular respiration occur in most plants?
Tems11 [23]

Answer:

Both photosynthesis and cellular respiration occur in plants. However, the rate of photosynthesis exceeds that of cellular respiration during the day when there is sunlight. The Chlorophyll pigment picks up energy from the photons and uses it to reduce carbon dioxide into carbohydrates. During the night, when there is little sunlight, the rate of photosynthesis drops down below that of cellular respiration, that breaks down these energy molecules made in photosynthesis to supply the plant’s cellular processes with energy.
