How is water potential $\psi$ affected by the presence of solutes and insoluble colloids?

When solute potential increases,then water potential would:

The movement of water molecules from a root cell to the adjacent cortical cell occurs based on what?

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.
$I. A \rightarrow B$ $II. B \rightarrow C$ $III. C \rightarrow A$ $IV. C \rightarrow B$

Identify the correct sentence:

As the concentration of the solution in the xylem vessels increases, its water potential ........
