Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Rate of photosynthesis does not depend upon
A
Quality of Light
B
Intensity of Light
C
Duration of light
D
Temperature
Explanation: 

Detailed explanation-1: -However, as light intensity increases further, photosynthesis rates are inevitably restricted by some other element.-For example, in the presence of a green leaf and optimum light and $CO 2$ levels, if the temperature is very low the plant cannot photosynthesize. Thus, the correct answer is light duration.

Detailed explanation-2: -The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

Detailed explanation-3: -The photosynthetic activity of light is wavelength dependent. Based on McCree’s work (McCree, 1971, 1972), photosynthetically active radiation is typically defined as light with a wavelength range from 400 to 700 nm.
