Answer 2

Answer:

• $Answer. Common salt when sprinkled on the grass causes the Plasmolysis of grass cell ultimately leading them to death. Hence, if we sprinkle some common salt on grass growing on a lawn, it is killed at the spot. ... Therefore, water flows out from the plant cell due to exosmosis. </li><li>Roots of the plant have whole sole responsibility to absorb water and minerals and when plants are uprooted absorption of water stops due to which leaves lacks water that's why leaves wilt.</li><li>In the evening, the stomata of the plants will close, and this will slow the loss of water through the leaves. Transplanting causes stress to the plant</li><li>The cytoplasm shrinks and the plasma membrane withdraws away from the cell wall and this the cell becomes flaccid. Hence a plant cell when kept in a hypertonic salt solution for about 30 minutes turns flaccid.</li><li>The potato cell has cell sap more in concentration inside the cell than in the surrounding water. ... Due to the flow of water in the cell, they become turgid and the cubes become firm and increase in size$
