Question

on each of the following situations what happens to the rate of photosynthesis:-
(ll) cloudy days
(ll) no rainfall in the area
(III) stomata get blocked due to dust

Answer 1

1. On cloudy day, due to low rate of sunlight, the rate of photosynthesis will be low.
2. If there is no rainfall in a particular area, the plant unable to get sufficient water for photosynthesis, this decrease the rate of photosynthesis, and plant will die.
3. When stomata get blocked due to dust, it unable to trap sunlight, and hence lead to the death of plant.
