Rate of photosynthesis increases with an increase in the intensity of light.
" The rate of photosynthesis increases with increase in intensity of sunlight till 0.02 % CO2 level and further increases with increase in intensity of sunlight only if CO2 level rises to 0.05%, " As per the video lesson and our book . But increase in CO2 level above 0.02% causes stomatal closure, which should reduce the rate of exchange of gases causing decrease in the rate of photosynthesis. Then why it's opposite happens?
