The hypertonic solution is more concentrated than the contents of the sap vacuole. The osmotic pressure of the solution is therefore higher than that of the sap vacuole. Water molecules thus move out of the plant cell and into the solution by osmosis. As water moves out of the cell, it becomes less and less rigid. At this point the plant cell is referred to as being flaccid. The process by which a plant cell loses water and becomes flaccid is referred to as plasmolysis
