Question

Differentiate between the following:
Plasmolysis and Deplasmolysis.

Distinguish Between

Solution

  Plasmolysis   Deplasmolysis
1. In this, the protoplasm of the cell shrinks away from the cell wall. It results in the flaccid condition of the cells and the plant. 1. In this, the protoplasm of the cell swells up and touches the cell wall. It results in the turgid condition of the cells and the plant.
2. Caused due to exosmosis. 2. Caused by endosmosis.
3. It takes place when a plant cell is kept in a hypertonic solution. 3. It takes place when a plasmolysed celI is kept in a hypotonic solution.
4. It results in the flaccid condition of the plant. 4. It results in the turgid condition of the plant.
