Answer Key / Explanation : (b) -

(b)

The movement of water occurs from low DPD cell to high DPD cell. DPD is equal but opposite to water potential (algebraic sum of solute or osmotic potential and pressure potential).

Cell

Water potential

(osmotic potential + pressure potential

DPD

A

-1+0.5=-0.5

+0.5

B

-0.6+0.3=-0.3

+0.3

C

-1.2+0.6=-0.6

+0.6

D

-0.8+0.4=-0.4

+0.4

So, the correct sequence of the path of movement of water is
