Question

Why do you think photosynthesis does not take place at night?

Answer 1

Photosynthesis:

1. Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (food) by using carbon dioxide, water and chlorophyll as raw materials.
2. Oxygen is evolved as a by-product of the process.
3. 6 CO₂ + 12 H₂O → Glucose (C₆H₁₂O₆) + 6 H₂O + 6 O₂
4. Sunlight acts as the light source essential for the process.
5. At night, due to absence of sunlight, photosynthesis stops.

Final answer: Photosynthesis does not take place at night due to absence of sunlight.
