Plasmolysis and deplasmolysis

Explanation

### Step-by-Step Solution

1. **Definition of Plasmolysis**:
- Plasmolysis is the process where the cell membrane shrinks away from the cell wall due to the loss of water from the cell. This occurs when a plant cell is placed in a hypertonic solution, which has a higher concentration of solutes outside the cell compared to the inside.

2. **Mechanism of Plasmolysis**:
- During plasmolysis, water molecules move out of the cell through osmosis, leading to the shrinking of the cell membrane. This process is known as exoosmosis.
