Question

name the factor which affect photosynthesis? answer in 10-15 words

Answer 1

When CO2, light and other factors are not limiting, the rate of photosynthesis increases with a rise in temperature, over a range from 6°C to about 37°C. Above this temperature, there is an abrupt fall in the rate and the tissue dies at 43°C. High temperatures cause the inactivation of enzymes and therefore affect the enzymatically controlled ‘dark’ reactions of photosynthesis.

The optimum temperature for the maximum falls between 20-30°C. Above 25-30°C the maximum rate is not maintained as the time factor begins to operate and the optimum temperature is reduced from 37°C to 30°C.
