Solution
In a hypertonic solution, the solution outside the cell has a higher solute concentration than the fluids inside the cell. Therefore, water flows out of the plant cell due to exosmosis. The cytoplasm shrinks, the plasma membrane withdraws away from the cell wall and the cell becomes flaccid. Hence, a plant cell, when kept in a hypertonic salt solution for about 30 minutes, turns flaccid.
