The real forces responsible for the movement of water from one cell to another cell is mainly
Osmotic Pressure (OP)
Turgor Pressure (TP)
Diffusion Pressure Deficit (DPD)
imbibition
C.
Diffusion Pressure Deficit (DPD)
The net force with which water is drawn into a cell is equal to difference of OP and TP, known as diffusion pressure deficit or suction pressure. DPD of pure water is maximum (= 1236 atm) solvent moves from cell of low DPD to high DPD. DPD, or SP= OP-TP.
