Crenation occurs when animal cells are exposed to a hypertonic solution, causing shrinkage, distortion, and often leave a scalloped appearance to the edge of the cell. A common reason for crenation in red blood cells is dehydration. It is also seen when pickling and salt-curing foods.
crenation
yes
The equivalent process to plasmolysis in an animal cell is called crenation. Crenation occurs when an animal cell shrinks and shrivels due to water leaving the cell, resulting in a decrease in cell volume.

An example of crenation is when red blood cells lose water and shrink in a hypertonic solution, such as saltwater. This causes the cells to have a scalloped appearance due to the contraction of the cell membrane.
Crenation occurs in a hypertonic solution, where the concentration of solutes outside the cell is higher than inside, causing water to leave the cell, leading to shrinkage and deformation of the cell.
In a hypotonic solution, red blood cells swell and undergo hemolysis, while in a hypertonic solution, they lose water and undergo crenation.
Crenation
Red blood cells would exhibit crenation in a 5.0 percent solution of glucose. This is because the solution has a higher solute concentration than the cytoplasm of red blood cells, leading to water leaving the cells causing them to shrink and exhibit crenation.
A 2 percent solution of sodium chloride is considered isotonic to red blood cells, meaning it will not cause crenation (shriveling) or hemolysis (bursting). Isotonic solutions have the same osmotic pressure as red blood cells, allowing for equilibrium and maintaining cell integrity.
