Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which solution will water move out of the cell resulting in the cell shriveling up?
A
Hypertonic
B
Isotonic
C
Hypotonic
Explanation: 

Detailed explanation-1: -In a hypertonic solution, the net movement of water will be out of the body and into the solution. A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.

Detailed explanation-2: -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.

Detailed explanation-3: -When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. 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.

Detailed explanation-4: -If a cell encounters a hypotonic environment, (like pure water for instance), water will diffuse into the cell and the cell will begin to swell. This can of course lead to an explosion of sorts.
