Question

explain diffusion pressure deficit with an example cleanly

Answer 1

Diffusion pressure deficit (DPD), is simply the net force or pressure that causes water to enter a plant cell. ... On the other hand, it can be defined as reduction in diffusion pressure (diffusing power) of pure water due to addition of solute in it. So, its value increases with solute concentration

Answer 2

The movement of gaseous molecule from the region of higher concentration to the region of lower concentration is known as diffusion.

Eg: if the cell is concentrated by oxygen inside it moves outside where the concentration is low obeying the law of diffusion.
