Question

Too much bright light and high temperature above 45 Celsius slowdownphotosynthesis why?

Answer 1

Answer:

Here is your Answer!!!

Explanation:

At temperatures above 68 degrees Fahrenheit, or 20 degrees Celsius, the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature. This is despite the increase of carbon dioxide diffusion into leaves. At a temperature above 104 degrees Fahrenheit – 40 degrees Celsius – the enzymes that carry out photosynthesis lose their shape and functionality, and the photosynthetic rate declines rapidly. The graph of photosynthetic rate versus temperature presents a curved appearance with the peak rate occurring close to room temperature. A greenhouse or garden that provides optimum light and water, but gets too hot, produces less vigorously.
