Answer 2

The reduction in the diffusion pressure of water in a solution over its pure state is called diffusion pressure deficit or DPD. Diffusion pressure deficit is also called suction pressure. It value is equal to the osmotic pressure or potential (OP) (positive value taken in bars or atm) of the solution in a cell or system minus the wall pressure (WP) (= turgor pressure, TP) which opposes the entry of water into it provided the external water is pure DPD = OP − WP (=TP)

Water is absorbed by a system having higher DPD from another system with lower DPD.

So, the correct answer is 'DPD = OP − TP'.
