Question

Two cells A and B are contiguous. Cell A has osmotic pressure 10 atm, turgor pressure 7atm 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

• Water flows from lower DPD to higher DPD. Here the DPD of two cells A and B are 3 and 5 atmosphere respectively.

Hence, water will move from cell A to B.
