Vedclass · Answer

(A) Xerophytes are plants adapted to survive in environments with little liquid water,such as deserts.To survive in water-deficient soils,xerophytes maintain a high Osmotic Pressure $(OP)$ within their cells.This high $OP$ helps them to absorb water from the soil even when the water potential of the soil is very low.Therefore,both the Assertion and the Reason are correct,and the high $OP$ is the reason why they can retain water effectively.

$A$: Xerophytes have high water-retaining capacity.
$R$: They have high $OP$.

Two cells $A$ and $B$ are contiguous. Cell $A$ has osmotic pressure $10 \ atm$,turgor pressure $7 \ atm$ and diffusion pressure deficit $3 \ atm$. Cell $B$ has osmotic pressure $8 \ atm$,turgor pressure $3 \ atm$ and diffusion pressure deficit $5 \ atm$. The result will be

The osmotic parameter determining the flow of water from one cell to another is:

If water enters a cell,the pressure exerted by its swollen protoplast against the cell wall is known as:
