Answer
When common salt is sprinkled on grass growing in lawn, the common salt acts as a hypertonic solution for the grass. The cells of grass start losing water, grass becomes flaccid and Plasmolysis occurs causing the protoplasm to go away from the cell wall. This creates gaps between the membrane and the cell wall. Grass cells shrink completely and ultimately get killed.
