Which one of the following statements about the process of photosynthesis is <strong>correct</strong>?

  1. A. Light energy is directly converted to kinetic energy which oxidizes carbon dioxide.
  2. B. Light energy is directly converted to chemical energy which causes reduction of water.
  3. C. Chlorophyll absorbs the chemical energy of light which causes oxidation of carbon dioxide.
  4. D. Chlorophyll absorbs light energy which causes splitting of water molecules and reduction of carbon dioxide.

Correct Answer: D. Chlorophyll absorbs light energy which causes splitting of water molecules and reduction of carbon dioxide.

Explanation

During photosynthesis, chlorophyll absorbs light energy to split water molecules (photolysis) releasing oxygen, while the energy is used to reduce CO_2 to form carbohydrates.
