Answer
When a plant cell is kept in a hypertonic salt solution, it starts losing water due to Plasmolysis. As the solution outside the cell has higher solute concentration than the fluids inside the cell so exosmosis occurs. In 30 minutes, the plant cell will lose its distended appearance, the cytoplasm will shrink and the plasma membrane will withdraw from the cell wall causing the plant cell to turn flaccid.
