Water potential can be calculated by

Explain why pure water has the maximum water potential.

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

$0.5 \ M$ sucrose solution develops a pressure of $15 \ bars$ in an osmometer. Which of the following statements is wrong for such a solution?

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

Water potential in plants is same as . . . . . . .
