Question

Two cells A and B are contiguous. Cell A has osmotic pressure 10 atm, turgor pressure - 7 atm and diffusion pressure deficit 3 atm. Cell B has osmotic pressure 8 atm, turgor pressure - 3 atm and diffusion pressure deficit 5 atm. The result will be

• A. Movement of water from cell B to A.
• B. No movement of water.
• C. Equilibrium between the two.
• D. Movement of water from cell A to B.

Answer 1

The correct option is D Movement of water from cell A to B.

The direction of movement of water is from low to high DPD, i.e., from 3 atm in cell A to 5 atm in cell B. Hence, option D is correct.
