Which term best describes the appearance of an animal cell when placed in a hypertonic solution?
A
turgid
B
plasmolysed
C
lysis
D
crenated
Explanation: 

Detailed explanation-1: -A red blood cell will swell and undergo hemolysis (burst) when placed in a hypotonic solution. When placed in a hypertonic solution, a red blood cell will lose water and undergo crenation (shrivel).

Detailed explanation-2: -When placed in a hypertonic solution, animal cells will shrink. As a hypertonic solution has less water and more solute content as compared to the interior of the cell, the animal cell when placed in this solution will lose water. Consequently, the cell shrinks.

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: -When a cell is placed into a hypertonic solution, water flows out of the cell, forming a shrunken and shriveled version of the cell. This is called crenation of the cell.

Detailed explanation-5: -Hypertonic solutions have a higher solute concentration than inside the cell. This causes water to rush out making the cell wrinkle or shrivel. This is clearly seen in red blood cells undergoing a process called crenation.
