When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.
What happens when a cell is placed in a hypotonic solution?
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 respond the same way as animal cells in a hypotonic solution, but the affects may not be as severe.
Why is blood serum hypotonic?
If the serum in the bloodstream were to contain a lesser concentration of solute than the solution within the red blood cells, this would make the serum hypotonic. The unequal osmotic pressure would then cause the water portion of the blood serum to diffuse into the red blood cells, causing them to swell.
What happens to a cell when water enters the cell?
Under these conditions, the osmotic pressure gradient forces water into the cell. Depending on the amount of water that enters, the cell may look enlarged or bloated. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies.
What causes water to diffuse into red blood cells?
Placing red blood cells in any solution which contains a lesser degree of solute than that of the solution within the cells will cause water to diffuse into them.
What happens when red blood cells are placed in a hypotonic solution?
When a red blood cell is placed in a hypotonic solution, there will be a net movement of free water into the cell. This situation will result in an increased intracellular volume with a lower intracellular solute concentration. The solution will end up with a higher overall solute concentration.
What happens when red blood cells are placed in water?
Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up and burst.

What happens when a red blood cell is placed in a solution which is hypertonic to the cell?
If the cell was placed in hypertonic solution, water would have moved out of the cell causing it to shrink. Red blood cells do not have the cell wall and contractile vacuoles and hence, would not be able to maintain their shape leading to their rupture.
What will happen to a red blood cell if you put it in a hypertonic hypotonic and isotonic solution?
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Will water move from the red blood cells to the beaker of water or from the beaker of water to the red blood cells?
Water movement is from a higher concentration to a lower concentration. In this case water will move out of the red blood cell into the beaker. The red blood cell will lose water and will shrink.
How does water move in a hypotonic solution?
In a hypotonic solution, water moves into the cell by endosmosis.
Does hypotonic and hypertonic water move?
If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic. Cells placed in a hypotonic solution will take in water across their membranes until both the external solution and the cytosol are isotonic.
When the cell is kept in a hypotonic solution then water moves?
Hypotonic solution is a solution, which contains lesser solute concentration. In such a case, the water molecules move from outside to the inside of the cell through the cell membrane. This process is called as endosmosis by which cell gains water and swells up.
Does hypertonic shrink or swell?
A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink.
When a red blood cell is placed in a hypertonic solution which of the following may occur quizlet?
A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypotonic solution will swell and potentially burst in a process called hemolysis.
Is hypertonic low to high concentration?
Hypertonic: The solution with the higher concentration of solutes. Hypotonic: The solution with the lower concentration of solutes.
What is hypotonic solution?
Hypotonic Solution. In a hypotonic solution, the solute concentration is lower than inside the cell. The prefix hypo means under or below in Latin. Under these conditions, the osmotic pressure gradient forces water into the cell. Depending on the amount of water that enters, the cell may look enlarged or bloated.
What happens when water enters a cell?
Depending on the amount of water that enters, the cell may look enlarged or bloated. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies.
What causes water to be exchanged between the intracellular and extracellular compartments?
Slight fluctuations in the solute concentration of the extracellular fluid throughout the day cause small amounts of water to be exchanged between the intracellular and extracellular compartments to maintain homeostasis. In contrast to hypotonic and isotonic solutions, a hypertonic solution has a higher solute concentration than inside the cell.
Why do cells rely on the body for water?
Cells don’t have the ability to regulate their water content (remember that osmosis is a passive process), so they rely on the body to provide an environment where intracellular and extracellular solute concentrations are equal or isotonic.
What is it called when water rushes out of the cell?
If this happens to red blood cells, it is called crenation .
What is the solute in osmosis?
Solute is the number of dissolved solids in a solution regardless of what they are. It can consist of proteins, carbohydrates, ions, hormones, etc. When discussing osmosis, comparison is made between the intracellular and extracellular (solution) solute concentrations. The concentration is also called the osmolarity of the solution.
What is the area outside the cellular compartment called?
The solution is the area outside the cellular compartment, also called the extracellular environment.
What happens when you put red blood cells in distilled water?
What Happens to Red Blood Cells When They Are Placed in Distilled Water? When red blood cells are placed in distilled water, which is hypotonic compared to the solution contained within the cells' membranes, the distilled water will diffuse into the red blood cells and cause them to burst. Placing red blood cells in any solution which contains ...
Why does distilled water diffuse into red blood cells?
Because distilled water contains a zero concentration of solute, it will predictably diffuse into a red blood cell in an attempt to equalize the osmotic pressure on both sides of the cell membrane.
What is the balance of osmotic pressure?
This balance of osmotic pressure is referred to as isotonicity. If the serum in the bloodstream were to contain a lesser concentration of solute than the solution within the red blood cells, this would make the serum hypotonic.
