Cells must be kept in an isotonic solution.
Isotonic means there is an equal concentration of solute both inside and outside of the cell.
A hypertonic solution means that there is more solute in the solution compared to within the cell. Water will move out of the cell to reach an isotonic state, causing the cell to shrink. That is BAD.
A hypotonic solution means that there is less solute in the solution compared to within the cell. Water will more into the cell to reach an isotonic state, causing the cell to swell and possibly burst or 'lyse'. That is also bad.
That's why cells must be kept in an isotonic solution.
2% glucose solution is considered as a hypotonic solution for that the solution will enter the semi-permeable membrane of the red blood cells causing the cells to explode or burst. Why? It's because RBCs have a higher concentration inside it than that of the 2% glucose solution so the solution will enter the cells.
The onion peel will shrink and dehydrate due to osmosis. The strong sugar solution will draw the water out of the onion cells, causing them to lose water and shrink in size.
Mitochondria are kept in sucrose solution to maintain their osmotic balance and prevent them from swelling or shrinking due to changes in their external environment. The sucrose solution helps to stabilize the mitochondria and maintain their structural integrity during the extraction process.
An isotonic solution for human red blood cells is a solution with the same osmotic pressure as the inside of the cells. This allows the cells to maintain their normal shape and size without losing or gaining water. Common examples of isotonic solutions include saline solutions and Ringer's lactate.
Water moves out of the cell in hypertonic solution.
When red blood cells are kept in a 10% glucose solution, water will flow out of the cells due to osmosis, causing them to shrink and become crenated. This is because the solution is hypertonic compared to the inside of the red blood cells.
If red blood cells (RBCs) are kept in a hypotonic solution, water will flow into the cells due to the higher concentration of solutes inside the RBC. This can cause the cells to swell and potentially burst, a process known as hemolysis.
2% glucose solution is considered as a hypotonic solution for that the solution will enter the semi-permeable membrane of the red blood cells causing the cells to explode or burst. Why? It's because RBCs have a higher concentration inside it than that of the 2% glucose solution so the solution will enter the cells.
If an alcohol-treated cell is kept in a hypertonic solution, it will likely shrink due to osmosis. The hypertonic solution has a higher solute concentration than the cell, causing water to move out of the cell and into the solution, leading to cell dehydration and shrinkage.
When red blood cells are placed in a 10% glucose solution, they will undergo crenation, which is the shrinking and deformation of the cells due to water loss through osmosis. The hypertonic solution causes water to move out of the cells, resulting in the cells losing their normal shape and structure.
The onion peel will shrink and dehydrate due to osmosis. The strong sugar solution will draw the water out of the onion cells, causing them to lose water and shrink in size.
When placed in an isotonic solution (i.e. a solution where the concentration of water molecules is roughly equal to the that within cells), there is equal diffusion of water into and out of the cells. Therefore, the cells find this environment suitable. In a hypotonic solution (i.e. a solution where the concentration of water molecules is much more than that within cells) water diffuses into cells as a result of which the cells swell. Excessive swelling causes the cells to burst, a phenomenon called cell lysis In a hypertonic solution (i.e. a solution where the concentration of water molecules is lesser than that within cells) water moved out from within cells to the surrounding medium. As a result of this, cells shrink.
If red blood cells (RBCs) are kept in a hypertonic solution, water will move out of the cells due to the higher concentration of solutes outside the cells. This causes the cells to shrink and crenate, leading to potential damage and dysfunction of the RBCs.
the molecules will pass from the salt solution to the cells.
A hypotonic solution has a lower solute concentration compared to the cells it surrounds. When cells are exposed to a hypotonic solution, water will move into the cells through osmosis, causing them to swell or potentially burst.
T-cells are not kept. They circulate through the blood stream. More are produced in the bone marrow and processed in the thymus.
Mitochondria are kept in sucrose solution to maintain their osmotic balance and prevent them from swelling or shrinking due to changes in their external environment. The sucrose solution helps to stabilize the mitochondria and maintain their structural integrity during the extraction process.
