Question

Cell A and Cell B are adjacent plant cells. In cell A ${\psi }_s=-20$ bars and ${\psi }_p=8$ bars. In cell B, ${\psi }_s=-12$ bars and ${\psi }_p=2$ bars. Then,

• A. water moves from cell A to cell B
• B. there is no movement of water between cell A and cell B
• C. water moves from cell B to cell A
• D. equal amount of water is simultaneously exchanged between cell A and cell B.

Answer 1

The correct option is C water moves from cell B to cell A

During osmosis, water moves from a region of low salt concentration to a region of high salt concentration. From the data given in the question, it is evident that water will move from Cell B to Cell A.

So, the correct answer is 'water moves from cell B to cell A'.
