Explanation:
There are three main aspects of photosynthesis
(i) Absorption of light energy by chlorophyll.
(ii)Photolysis of water
(iii) combination of water and CO2 to form carbohydrates.
The second and the third aspects of photosynthesis are controlled by the availability of water. Plants absorb water from the soil through their root hairs and it moves up to the leaves by capillary action.
Hence, if there is no rain (drought), the soil will lack water and so does the plant thereby hindering the uptake of water for the second and third stages of photosynthesis.
