Question

Give three uses of plasmolysis in our daily life.

Answer 1

Plasmolysis:

1. Plasmolysis is the contraction or shrinking of a plant cell's protoplasm caused by water loss.
2. Plasmolysis is a rare occurrence in nature that happens as a product of osmosis.
3. The process of plasmolysis is divided into three stages: Incipient plasmolysis, Evident plasmolysis, and Final plasmolysis.

Three uses of plasmolysis in our daily life are as follows:

1. Salting of pickles: To prevent the pickles from spoiling through germs or microbes in the air, the germ cells are plasmolyzed. The water is sucked from them, rendering them useless and preventing them from growing further.
2. Excess fertilizers are applied to crops, causing the root cells to plasmolyze and die. As a result, the crop's yield is reduced.
3. Some grasses spread like weeds on lawns and playgrounds. Because their roots remain on the ground, they cannot be cultivated by hand. Common salt is applied to their base to prevent them from expanding. This destroys the root cells by removing water from them, preventing them from growing.
