Detailed explanation-1: -A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis. An isotonic solution is any external solution that has the same solute concentration and water concentration compared to body fluids.

Detailed explanation-2: -When an animal cell is placed in a hypertonic solution, then water moves out of the cell as a result of exosmosis. So, when an animal cell will be placed in a hypertonic solution then it would lose water and shrink.

Detailed explanation-3: -If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.

Detailed explanation-4: -In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a proces s called plasmolysis. Animal cells tend to do best in an isotonic environment, plant cells tend to do best in a hypotonic environment.

Detailed explanation-5: -When red blood cells are in a hypertonic (higher concentration) solution, water flows out of the cell faster than it comes in. This results in crenation (shriveling) of the blood cell.
