Vedclass · Answer

(D) Water is a critical factor affecting photosynthesis in the following ways:$1$. Water acts as a reactant in the light-dependent reactions (photolysis of water),so its deficiency directly limits the rate of photosynthesis.$2$. Water stress leads to the closure of stomata,which restricts the entry of $CO_2$ into the leaves,thereby reducing the rate of photosynthesis.$3$. Water stress causes wilting of leaves,which reduces the effective surface area of the leaves and their metabolic activity,further decreasing the rate of photosynthesis.Therefore,all the given statements are correct.
