Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of solution does water escape the cell causing it to shrivel?
A
Hypertonic
B
Hypotonic
C
Isotonic
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: -Tonicity in living systems If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink.

Detailed explanation-3: -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.

Detailed explanation-4: -Hyper is a Latin prefix meaning over or above. Therefore, a hypertonic solution has more solutes than the intracellular environment, so water will leave the cell to try to achieve equilibrium. If enough water is lost, the cell will take on a wrinkled or shriveled appearance.

Detailed explanation-5: -A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.
