Correct Answer:
suction pressure
Explanation:
D.P.D. (diffusion pressure deficity) is the amount by which the diffusion pressure of a solution is lower than that of its pure solvent. The DPD of a cell denotes the net pressure that causes water to enter cell. DPD = OP – WP and since WP = TP thus DPD = OP – TP. D.P.D is also known as suction pressure.
