Question

The optimum temperature range for photosynthesis is ______.

विकल्प

• 25-35°C

• 10-15°C

• 35-40°C

• 20-25°C

Answer 1

The optimum temperature range for photosynthesis is 35-40°C.

Explanation:

Light and CO₂ increase the rate of photosynthesis up to a saturation limit. Temperature peaks at 35°C but stops at 40°C due to enzyme destruction. Water scarcity closes stomata, lowering CO₂ intake.
