Vedclass · Answer

(D) Water potential $(\Psi_w)$ is the measure of the potential energy of water in a system. Water always moves from a region of higher water potential (less negative) to a region of lower water potential (more negative).Given: $\Psi_A = -1000$ and $\Psi_B = -2000$.Since $-1000 > -2000$,solution $A$ has a higher water potential than solution $B$.Analysis of statements:$(i)$ Osmotic pressure is inversely related to water potential. Since $B$ has a lower water potential,it has higher solute concentration and thus higher osmotic pressure. Statement $(i)$ is incorrect.$(ii)$ Osmosis occurs from higher water potential $(A)$ to lower water potential $(B)$. Thus,osmosis occurs toward $B$. Statement $(ii)$ is correct.$(iii)$ Higher water potential implies more free water molecules. Since $\Psi_A > \Psi_B$,$A$ has more free water molecules. Statement $(iii)$ is correct.$(iv)$ At equilibrium,the net movement of water stops,and both sides reach the same water potential. Statement $(iv)$ is correct.$(v)$ Osmosis occurs toward $B$,not $A$. Statement $(v)$ is incorrect.Therefore,statements $(ii), (iii),$ and $(iv)$ are correct.
