**Diffusion Pressure Deficit (DPD)** of a fully turgid plant cell is:

Question

Accepted Answer

B. Zero (cell can absorb no more water)

DPD = OP − TP.
In a fully turgid cell, turgor pressure equals osmotic pressure
⇒ DPD = 0 (cell cannot absorb more water).
In a flaccid cell (TP = 0), DPD = OP.

Answer

Maximum (equal to osmotic pressure)

Answer

Negative

Answer

Equal to wall pressure
