Urea is isosmotic to the intracellular fluid of red blood cells, but because the membranes of the blood cells are permeable to urea. Urea enters the cell at a much more rapid rate than other permeable solutes (because of the steep concentration gradient) and the cell fills to it bursts.
What else can I help you with?
What type of solution will lyse protoplast?
A hypertonic solution high in salts or sugars will typically lyse protoplasts by causing water to leave the cell through osmosis, leading to cell burst.
Why human cell burst?
If you put a cell in a hypotonic environment, such as a blood cell in water, it will swell up due to osmosis and lyse.
If an erythrocyte is placed in a hypertonic solution what will it do?
If a human red blood cell is placed in a hypotonic environment, the red blood cell will swell and eventually burst. The reason for this is because a hypotonic solution has a higher osmotic pressure compared to the cytoplasm of the red blood cell. Thus, the water from the hypotonic solution moves into the red blood cell causing it to rupture.
What would happen if you placed an human red blood cell in a hypotonic environment?
hypotonic solution will cause the blood cell to swell up and maybe lyse or be destroyed. Hypotonic solution contains low solute and high water concentration. To reach equilibrium or blanace the difference in the cell and out side of the cell water will move in to make the solute in the cell equal the solute outside the cell
Can a solution be isosmotic but not isotonic?
Reasons and explanation -Isotonic solutions contain only non-penetrating solutesand have the same osmotic pressure as the cells they surround. They are neither absorbed nor do they absorb anything from the surrounding cell. They have the same concentration of salt as the blood and human cells in the body.whereasIsosmotic solutions contain both penetrating and non-penetrating solutes. They have the same osmotic pressure of the surrounding cells. Penetrating solutes are solutes that can pass through the membrane of the cell and increase the osmotic pressure in the cell. This forces the cell to absorb more water to equalize the difference in pressure. This may lead to bursting of the cell when too much water is absorbed.
Would hypertonic or hypotonic blood serum cause hemolysis?
If a cell is placed into a hypotonic solution, the water will flow into the cell causing it to swell and possibly lyse. If a cell is placed into a hypertonic solution, the water will flow out of the cell causing it to crenate. So hemolysis occurs when the red blood cells lyse.
What type of solution will lyse protoplast?
A hypertonic solution high in salts or sugars will typically lyse protoplasts by causing water to leave the cell through osmosis, leading to cell burst.
Is isotonic better than hypotonic and hypertonic?
Yes if you are speaking about use with blood. An isotonic solution has the same concentration of specific elements as you blood preventing cellular damage. If you used a hypertonic solution all the water would leave the cell and it would crenate. If you use a hypotonic solution water would move into the cell quickly and the cell would burst (lyse).
What could you do to reduce interference from red blood cells?
Mix the blood in a hypotonic solution, which will cause the RBCs to lyse.
Why does the shape of a red blood cell change in different solutions?
The shape of a red blood cell changes in different solutions due to osmosis, where water moves in or out of the cell to reach equilibrium with the surrounding solution. In a hypotonic solution, the cell swells and may burst (lyse) due to excess water entering the cell. In a hypertonic solution, the cell shrinks and becomes crenated due to water leaving the cell.
Lower concentration of solutes outside the cell than inside the cell?
Hypotonic solution. Water will move into the cell, possibly causing it to swell and burst (lyse).
Why human cell burst?
If you put a cell in a hypotonic environment, such as a blood cell in water, it will swell up due to osmosis and lyse.
A cell would plump with water and possibly lyse in what solutions?
A cell would plump with water and possibly lyse in hypotonic solutions, where the external solution has a lower solute concentration than the cytoplasm of the cell. Water would move into the cell to equalize the solute concentration, causing the cell to swell and potentially burst.
What happens when normal Red blood Cells are placed in hypotonic solution?
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 gradient solutes will move out of the red blood cell causing water to go into the cell. This will cause the cell to swell up and eventually Lyse.
If an erythrocyte is placed in a hypertonic solution what will it do?
If a human red blood cell is placed in a hypotonic environment, the red blood cell will swell and eventually burst. The reason for this is because a hypotonic solution has a higher osmotic pressure compared to the cytoplasm of the red blood cell. Thus, the water from the hypotonic solution moves into the red blood cell causing it to rupture.

To reach equilibrium or blanace the difference in the cell and out side of the cell water will move in to make the solute in the cell equal the solute outside the cell
Why do cells or lyse when placed in hypotonic solution?
Cells lyse in a hypotonic solution because the concentration of solutes outside the cell is lower than inside the cell, causing water to move into the cell by osmosis. This influx of water causes the cell to swell and eventually burst, leading to cell lysis.
