What will be the direction of movement of water when a solution $A$ having a water potential of $-9 \ bars$ and another solution $B$ having a water potential of $-4 \ bars$ are separated by a semipermeable membrane?

Water potential is same as . . . . . . .

If solution $A$ has $\Psi = -1000$ and $B$ has $\Psi = -2000$ are separated by a semipermeable membrane,which sentences are correct?
$(i)$ Solution $A$ has greater osmotic pressure
$(ii)$ Osmosis occurs toward $B$
$(iii)$ $A$ has more free water molecules
$(iv)$ At equilibrium,both will have the same water potential
$(v)$ Osmosis occurs toward $A$

Find the correct pathway of water movement in the given presentation of cells.

$A$ $0.1 \ M$ solution of a solute has a water potential of:

Why is the water potential of pure water zero?
