When a plant cell is placed in a solution that is hypertonic relative to the cytoplasm, water moves out of the cell and the cell shrinks. In the case of a red blood cell, isotonic conditions are ideal, and your body has homeostatic stability-maintaining systems to ensure these conditions stay constant. There is no net water movement, so there is no change in the size of the cell. BBC Radio 1 BBC 1Xtra. There are some different explanations out there.
