Question

What is meant by plasmolysis? How is it practically useful?

Answer 1

Plasmolysis:

1. Plasmolysis happens when the water leaves the cell, and the cell membrane shrinks away from the cell wall of a plant cell.
2. This occurs when a cell is placed in the hypertonic solution.
3. The plasmolysis process is frequently reversible.

Applications:

1. It serves a crucial function in the preservation of meat, jellies, and other food products, preventing bacteria and fungus from destroying them.
2. Pickles are salted.
3. Spraying weedicides to kill weeds in orchards and agricultural fields.
4. It aids in avoiding the development of plants in the wall cracks. Such plants are salted to cause plasmolysis, which kills the undesirable plants.
