Question

DPD of a cell mainly depends upon

• A. OP
• B. Water Solute Pressure
• C. WP
• D. None of the above

Answer 1

The correct option is A OP

Diffusion Pressure Deficit or DPD is basically the suction pressure. DPD is the reduction in diffusion pressure in water in solution over its pure state due to presence of solute.

DPD = OP (In solution)

DPD = OP -TP (In cell where TP stands for turgor pressure)

Thus, DPD primarily depends on osmotic pressure (OP), i.e. option A is correct.
