When the water potential of leaf cells decreases, water from the leaf veins moves into which of the following?

Why is the water potential of pure water zero?

Identify the correct sentence:

Study the following table showing the components of water potential in closely arranged mesophyll cells namely $A, B$ and $C$.

Cell	Osmotic Potential (MPa)	Pressure Potential (MPa)
$A$	$-0.21$	$0.05$
$B$	$-0.22$	$0.02$
$C$	$-0.23$	$0.05$

Identify two of the following,which show correct direction of water movement between two cells.
$I. A \rightarrow B$ $II. B \rightarrow C$ $III. C \rightarrow A$ $IV. C \rightarrow B$

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 $A$

Water potential is affected by
