Detailed explanation-1: -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. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Detailed explanation-2: -If we place a cell in the hypertonic solution like in sugar or salt solution, the cell will shrink. It is because the movement of water takes place from lower solute concentration to higher solute concentration i.e from inside sugar solution to attain equilibrium. It results in shrinkage of the cell.

Detailed explanation-3: -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-4: -In a solution with a lower water potential than the cell itself, animal cells will shrink.

Detailed explanation-5: -Animal cells gain water, swell and burst in a more dilute solution (this is called haemolysis) lose water and shrink in a more concentrated solution (they become crenated or wrinkled)
