Question

20 which statement accurately describes the energy needs for photosynthesis and cellular respiration? a light energy is needed for cellular respiration, but not for photosynthesis. b light energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration. c chemical energy in the form of glucose is needed for photosynthesis, and light energy is needed for cellular respiration. d chemical energy in the form of glucose is needed for both cellular respiration and photosynthesis.

Explanation:

Photosynthesis uses light energy to convert carbon - dioxide and water into glucose and oxygen. Cellular respiration uses the chemical energy stored in glucose to produce ATP for the cell's energy needs.

Answer:

B. Light energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.
