Question

name the various factors that affect the rate of photosynthesis?

Answer 1

Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature.
rate of photosynthesis plotted against light intensity. the rate begins to slow as the light intensity continues to increase
Light intensity
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.
Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.
If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.
If you plot the rate of photosynthesis against the levels of these three limiting factors, you get graphs like the ones above.
In practice, any one of these factors could limit the rate of photosynthesis.

Answer 2

the factors that affect the photosynthesis is 
sunlight
chlorophyll 
the carbon dioxide
water present in the atmosphere
