Question

Difference between osmotic pressure and diffusion pressure deficti

Answer 1

The difference between diffusion pressure of pure water and solution is called diffusion pressure deficit (DPD). ... As the cell absorbs more and more water its Total Pressure increases and Osmotic Pressure decreases. When a cell is fully turgid, its OP is equal to TP and DPD is zero.

Answer 2

Turgor Pressure(T.P) is defined as the amount of pressure inside a cell solely due to its water content, whereas Osmotic Pressure(Pi) is defined as the pressure required to stop osmotic flow between the cell and a pure solvent when the pressure exerted by water is zero
