A) OP
B) TP
C) DPD
D) BP
Correct Answer: C
Solution :
DPD = Diffusion Pressure Deficit, is the reduction in diffusion pressure or free energy of a solvent in an osmotic system over its pure solvent. It is dependent upon OP or \[{{\text{ }\!\!\psi\!\!\text{ }}_{\text{S}}}\]of the system, OP or\[{{\text{ }\!\!\psi\!\!\text{ }}_{\text{S}}}\] of solution and the resistance that system puts against entry of more solvent into it. DPD or\[{{\text{ }\!\!\psi\!\!\text{ }}_{\text{w}}}\] determines whether a cell will lose or gain water from an external solution or adjacent cells or the movement of water from cell to cell. OP is the potential pressure than can be developed in a solution when it is separated from pure solvent by a semipermeable membrane. It helps in retaining water inside cells. TP is the Turgor Pressure or hydrostatic pressure, develops in a system due to osmotic entry of solvent in it. It is essential for growth of cells. BP denotes the Blood Pressure in man.
