My cells are Shriveled! What state are my cells in?
A
Hypertonic
B
Hypotonic
C
Isotonic
D
Diffusion
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 a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Diagram of red blood cells in hypertonic solution (shriveled), isotonic solution (normal), and hypotonic solution (puffed up and bursting).

Detailed explanation-4: -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-5: -In a hypertonic environment, cells use membrane proteins called aquaporin channels to take advantage of the osmotic pressure gradient and shift water towards the higher concentration medium. Cells are permeable to water, and thanks to this, they can shrink and elevate the concentration of intracellular solutes.
