    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 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 cells

    D) movement of water from cell A to B

    Correct Answer: A

    Solution :

    [a] The water moves from lower DPD to higher DPD. Cell A possesses diffusion pressure deficit of \[-\,3\]atm and cell \[B-5\] atm DPD. Hence, it will move from cell B to A.
