Solution

Plant cells are enclosed by a rigid cellwall. When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but thecell wall prevents it from bursting. Theplant cell is said to have become "turgid" i.e. swollen and hard.

Whereas If you kept it in hypertonic solution,

If a plant cell is placed in a hypertonic solution, the plant cell loses water and hence turgor pressure by plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane and making the plant cell shrink and crumple
