Vedclass · Answer

(B) Applying salt to the soil creates a hypertonic environment around the roots of the plants.Due to the high concentration of salt in the soil,the water potential of the soil becomes lower than that of the plant cells.This causes water to move out of the plant cells into the soil through the process of exosmosis.As a result,the plant cells undergo plasmolysis,leading to the wilting and eventual death of the weeds.Grass is often more tolerant to specific salt concentrations or is managed such that the salt application is localized to the weeds,preventing significant damage to the lawn grass.

Salt is applied to tennis lawns to kill weeds. How does salting tennis lawns help in killing weeds without affecting the grass?
