Question 5

Mary sprinkled 5 kg of common salt on the grass growing on her lawn. After a couple of days, she observed that the grass had wilted and died. This was due to which of the following conditions?

  1. Endosmosis
  2. Turgidity
  3. Deplasmolysis
  4. Plasmolysis
Answer

Plasmolysis

Reason — The salt makes the soil solution hypertonic. When cells come in contact with the soil solution, the cell sap comes out by exosmosis resulting in shrinkage of cell known as plasmolysis. Plasmolysis cause wilting of plant.
