Shrinking of the protoplasm due to loss of water by osmosis is known as the plasmolysis. It occurs when the amount of water molecules is high in the cell than the outside; the movement of water molecules occurs resulting in the shrinkage of the protoplasm and the detachment of the plasma membrane from the cell wall.
The cytolysis is the bursting of the cell due to the entering of the excess amount of water; which created an imbalance in the osmotic pressure.
