Question

The correct sequence of photosynthesis in green plants is :

• A. Absorption of light by Chlorophyll → Splitting of water to H₂ and O₂ → Reduction of CO₂ → Carbohydrate formation
• B. Splitting of water to H₂ and O₂ → Reduction of CO₂ → Absorption of light by Chlorophyll → Carbohydrate formation
• C. Splitting of water to H₂ and O₂ → Absorption of light by Chlorophyll → Reduction of CO₂ → Carbohydrate formation
• D. Absorption of light by Chlorophyll → Reduction of CO₂ → Splitting of water to H₂ and O₂ → Carbohydrate formation

Answer 1

The correct option is A

Absorption of light by Chlorophyll → Splitting of water to H₂ and O₂ → Reduction of CO₂ → Carbohydrate formation

In the process of photosynthesis, first light is trapped by chlorophyll and there is splitting of water into oxygen and hydrogen [ light-dependent reactions]. This is followed by reduction of carbon dioxide into carbohydrates by various plant enzymes [ light independent reactions].
