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.
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.
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.
Red blood cells (RBCs) as seen under the microscope in isotonic, hypotonic and hypertonic solutions. A few white blood cells can also be seen with the red blood cells. RBCs contain hemoglobin, a ...
Well use red blood cells as an example. Normal sized red blood cells are round and are concave. When these cells exist in an isotonic solution one in which the concentration of solutes is the same inside the cell as outside the cell water exits and enters the cell at the same rate. This is the normal balance of a red blood cell. Hypotonic ...
A red blood cell placed in a hypotonic solution will swell and potentially burst in this process How do you prevent crenation or hemolysis? A cell must be placed in an isotonic solution such as 0.9%(m.v) NaCl or 5% (m/v) flucose.
Best Answer: When animal cells such as red blood cells are placed in a hypotonic solution (distilled water), water molecules diffuse into the red blood cells by osmosis. The red blood cells gain water and swell and finally burst because they have no cell walls. the red blood cells are said to undergo haemolysis.
Thus the sucrose solution is isotonic and the urea solution is hypotonic. The differential effect of these solutions on red cell volume is related to the permeability of the plasma membrane to sucrose and urea. The red blood cell membrane contains uniporters for urea (see Chapter 4).
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.
Hypotonic means that the concentration gradient is lower than what ever your comparing it to (in this case a red blood cell) since the net movement of solute goes from high to low concentration ...
