question_answer

If a cell A with DPD 4 bars is connected to cell B, C, D whose Osmotic Pressure (OP) and Turgor Pressure (TP) are respectively 4 and 4, 10 and 5, 7 and 3 bars, the flow of water will be:

A)  B to A, C and D

B)  A and D to B and C

C)  C to A, B and D

D)  A to B, C and D

Correct Answer: A

Solution :

 Diffusion Pressure Deficit is the value by which the diffusion pressure of a solution is lower than that of pure solvent. It is also known as suction pressure. The movement of water occur from a cell having lower DPD to a cell having higher DPD.
