Question

Choose the correct answers from the alternatives given.
If cell A with OP = 5 and TP = 4 is surrounded by cells with OP = 3 and TP = 1, what will be the direction of water movement?

• A. From other cells to cell A
• B. From cell A to other cells
• C. Water will not move
• D. Data insufficient

Answer 1

The correct option is B From cell A to other cells

DPD or diffusion pressure deficit determines the flow of water. Water moves from low DPD to high DPD.

DPD is given by: DPD = OP - TP.

In cell A, DPD = 5 - 4 = 1.

In other cells, DPD = 3 - 1 = 2.

Since water moves from low DPD to high DPD, here the movement occurs from cell A to the other cells.

Hence, the correct answer is 'From cell A to other cells'.
