Detailed explanation-1: -A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.
Detailed explanation-2: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell.
Detailed explanation-3: -When a cell is kept in hypertonic solution for a long time it shrinks. The water inside the cell moves out as the concentration outside the cell is higher. As a result, the cell shrinks. This is also known as plasmolysis.
Detailed explanation-4: -2.221. Osmotic lysis with a hypotonic solution causes the cells to swell and burst. Swelling of the cell, caused by the inward movement of water, may also enhance the uptake of detergents into the cellular membrane.
Detailed explanation-5: -When a cell is placed in a hypertonic solution, a cell will lose water and shrink. A plant cell is surrounded by a very rigid cell wall, so a cell shrinks but by slowly losing water plasma membrane moving away from the cell wall and this process is known as plasmolysis.
