Question

Two adjacent cells A and B are being studied. Cell A has OP of $10$ atm and TP of $6$ atm. Cell B has OP of $10$ atm and TP of $4$ atm.
Movement of water will occur from.

• A. Cell A to cell B
• B. Cell B to cell A
• C. No movement of water
• D. Cannot be determined

Answer 1

The correct option is A Cell A to cell B

For Cell A: DPD=OP−TP=10−6=4atmDPD=OP−TP=10−6=4atm
For Cell B: DPD=OP−TP=10−4=6atmDPD=OP−TP=10−4=6atm
As water moves from a cell with lower DPD to a cell with higher DPD, therefore water will move from cell A to cell B.
