Assertin : Plant utilize 5-10% of the absorbed water in photosynthesis.
Reason : Reduced leaf hydration decrrease the photosynthesis.

Options

A. If both the asserition and the reasion are true and the reason is a correct explanation of the assertion
B. If both the assertion and reasoni s not a correct ecplanation of the assertio
C. If the assertion is true but the reason is false
D. If the assertion is false but reason is true

Answer

E

Explanation

Less than 1% of the total water absorbed is utilized in photosynthesis. The rest is lost in transpiration. Even a slight increase in transpiration reduces the leaf hydration that cuts down photosynthesis by causing stomatal closure and hence decreased `CO_(2)` absorption, loss of leaf turgidity, reduced absorption of solar radiations and decrease enzymatic activity.
