Question

Under what conditions do photosynthesis and cellular respiration occur in most plants? under what conditions do photosynthesis and cellular respiration occur in most plants? photosynthesis and cellular respiration occur in both the dark and the light. photosynthesis occurs only in the light, and cellular respiration occurs in both the dark and the light. photosynthesis and cellular respiration occur only in the light. photosynthesis occurs only in the light, and cellular respiration occurs only in the dark.

Answer 1

The correct answer is: photosynthesis occurs only in the light, and cellular respiration occurs in both the dark and the light.
Light is necessary for the first stage of the photosynthesis-light dependent reactions. These reactions occur in the presence of sunlight, and use that light energy to produce ATP and NADPH. Cellular respiration does not depend on light, it occurs all the time.

Answer 2

Photosynthesis occurs only in the light while cellular respiration occurs in both the dark and the light. Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy. The process takes in carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into ATP, and the release waste products.
