The term water potential was proposed by

Water potential is denoted by $..........$.

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 statement:
Water flows between two cells . . . . . . .

Define water potential and solute potential.

Provide definitions/explanations for the following terms:
$(1)$ Water potential
$(2)$ Translocation of substances
