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

Does the plant use the whole water absorbed during photosynthesis?

Land plants utilize for photosynthesis

Assertion : CO_2 is utilized in dark reaction of photosynthesis. Reason : CO_2 as one of the raw material enters the leaves through stomata.

In green plants, during photosynthesis water act as:

In green plants, during photosynthesis water act as:

Assertion :- Indirectly water stress leads to decrease in photosynthesis. Reason :- Water stress leads to wilt of leaves and minimise their surface area

Assertion (A) : Leaf shows maximum photosynthesis at green wavelength. Reason (R) : Leaf is green in colour and hence photosynthesis is maximum at green wavelength.
