A hypotonic solution has a lower solute concentration than the inside of the red blood cells. Because of this, the osmotic forces would cause water from the solution to enter the cells. If left uncontrolled, the cells will eventually stretch and burst in a process called lysis.


An iso-osmolar solution can be hypotonic if the solute is able to penetrate the cell membrane. For example, an iso-osmolar urea solution is hypotonic to red blood cells, causing their lysis. This is due to urea entering the cell down its concentration gradient, followed by water.


When a red blood cell is placed in a hypertonic solution, it shrinks as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.


When the solution outside of the red blood cells has a lower osmotic pressure than the cytoplasm of the red blood cells, the solution is hypotonic with respect to the cells. The cells take in water in an attempt to equalize the osmotic pressure, causing them to swell and potentially burst.


In contrast, a hypotonic solution has less solute than inside the cell, like putting a cell in distilled water. In this situation, water enters the cell, and if left uncontrolled it can cause the cell to burst and die. The image above shows what happens to red blood cells in hypertonic, isotonic, and hypotonic solutions.


What Happens to a cell in a hypotonic solution. This is what happens: since the cell is in the liquids in your body that has lower concentration. the water will leave the cell to try and make the concentration equal both within the cell and outside the cell.

In contrast to hypotonic and isotonic solutions, a hypertonic solution has a higher solute concentration than inside the cell. When this happens, the osmotic gradient causes water to rush out of the cell and it becomes wrinkled or shriveled. If this happens to red blood cells, it is called crenation. Plant Cells
