Solution
Deplasmolysis occurs when a plasmolysed cell is placed in Tap water.
Explanation:
One hypotonic solution is tap water. Because the concentration of water outside the cell is higher, water moves within the cell. Subsequently, the cell expands and turns turgid. This is known as deplasmolysis.
