Plasmolysis is the shrinking of the protoplasm as a result of water loss from osmosis when a cell comes in contact with a hypertonic solution.Plant cells kept in hypertonic solution will start losing water by the process of exosmosis as there is lesser concentration of solvent molecules than the fluid inside the cell so the solvent molecules are forced outside the cell from the region of higher concentration to the lower concentration.The cell turns flaccid. On further loss of water, the protoplasm shrinks and moves away from the cell wall and the cell gets plasmolysed.
