Describe the process/mechanism of plant cell plasmolysis with an example and a labelled diagram.

(N/A) Plasmolysis is the process in which plant cells lose water in a hypertonic solution,causing the protoplast to shrink away from the cell wall.
$1$. Types of Solutions:
- Isotonic Solution: An external solution that balances the osmotic pressure of the cytoplasm.
- Hypotonic Solution: An external solution that is more dilute than the cytoplasm,causing water to enter the cell.
- Hypertonic Solution: An external solution that is more concentrated than the cytoplasm,causing water to move out of the cell.
$2$. Mechanism of Plasmolysis:
- When a living plant cell is placed in a hypertonic solution,water moves out of the cell due to osmosis.
- Water is first lost from the cytoplasm and then from the vacuole.
- As water leaves,the cell membrane shrinks away from the cell wall,a state known as plasmolysis.
- The cell is said to be plasmolysed when the space between the cell wall and the shrunken protoplast is filled with the external hypertonic solution.
