For a solution at atmospheric pressure,$\psi_{w}$ is equivalent to

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

What is the pressure potential $({\Psi _p})$ of a flaccid cell?

Osmotic potential is

The water potential of pure water is

When water is lost through transpiration from the leaves, what happens to the water potential of the leaf cells?
