Explanation:
The synthesis of carbon dioxide and water is purely catalyzed by light energy from the sun. The light energy is used to synthesize useful organic molecules and produce oxygen gas.
- Photosynthesis is light catalyzed.
- Green plants manufacture their food using sunlight.
- A special pigment in plant called chlorophyl traps the sunlight.
- Carbon dioxide and water will react when the light energy from the sun is made available in plant leaves.
- This will then produce organic compounds with rich chemical energy.
- Oxygen gas is given off as a by product.
