What is meant by hypotonic in biology?

Biology definition: A hypotonic solution is a solution that has lower osmotic pressure than another solution to which it is compared. It may also mean a solution that contains a lower amount of solute as compared with the solute concentration in the other solution across a semipermeable membrane.

What is hypotonic short answer?

Definition of Hypotonic Solution A hypotonic solution means something that has a lower solute concentration in comparison to another solution. A solution is not hypotonic, isotonic or hypertonic if there is no solution for comparison. It helps scientists to describe cells.

What is hypertonic in biology?

A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.

What is hypotonic and hypertonic in biology?

A hypotonic solution is one in which the concentration of solutes is greater inside the cell than outside of it, and a hypertonic solution is one where the concentration of solutes is greater outside the cell than inside it.

What is hypotonic example?

Hypotonic Solution Definition The solute is the substance present in a lower amount, and the solvent is the substance present in greater amount. A hypotonic solution example is salt water. The salt is the solute, and the water is the solvent.

What is a hypotonic and hypertonic solution?

A solution with a lower solute concentration as compared to a solvent is called a hypotonic solution. In contrast, a solution with a high solute concentration as compared to a solvent is called a hypertonic solution.

What is hypertonic condition?

Hypertonic refers to a solution with higher osmotic pressure than another solution. In other words, a hypertonic solution is one in which there is a greater concentration or number of solute particles outside a membrane than there are inside it.

Why is hypotonic solution used?

Hypotonic solutions are used when the cell is dehydrated and fluids need to be put back intracellularly. This happens when patients develop diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemia.

Why do hypotonic cells swell?

If placed in a hypotonic solution, water molecule s will enter the cell, causing it to swell and burst. Plant cells (bottom panel) become plasmolyzed in a hypertonic solution, but tend to do best in a hypotonic environment.

What happens to a cell in a hypotonic solution?

A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis. These three examples of different solute concentrations provide an illustration of the spectrum of water movement based on solute concentration through the process of osmosis.

Does hypotonic shrink or swell?

Although the presence of a hypotonic or hypertonic solution initiates swelling or shrinking, respectively, often the volume change is not maintained. A cell that initially swells when placed in a hypotonic medium may eventually lose some of its acquired volume: it undergoes a regulatory volume decrease or RVD.

What is isotonic in biology?

Isotonic solution: A solution that has the same salt concentration as cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients.

What’s the difference between hypertonic and isotonic?

The main difference between isotonic hypotonic and hypertonic solutions is that isotonic solutions are solutions having equal osmotic pressures and hypotonic solutions are solutions having a lower osmotic pressure whereas hypertonic solutions are solutions with a high osmotic pressure.

What is hypertonic fluid?

Hypertonic fluids contain a higher concentration of solute compared to plasma and interstitial fluid; this creates an osmotic gradient and drives fluid from the interstitial space into the intravascular space.

What does hypertonic mean easy?

Definition of hypertonic 1 : exhibiting excessive tone or tension a hypertonic baby a hypertonic bladder. 2 : having a higher osmotic pressure than a surrounding medium or a fluid under comparison.

What are examples of hypertonic?

Hypertonic Solutions. Hypertonic solutions have a higher concentration of dissolved particles than blood. An example of hypertonic IV solution is 3% Normal Saline (3% NaCl). When infused, hypertonic fluids cause an increased concentration of dissolved solutes in the intravascular space compared to the cells.

Is hypotonic more or less water?

These terms become clearer, if you remember that “tonic” and water are different, and that “hyper” means lots, and “hypo” means less. So, a hypertonic solution is one that contains less water, and more of something else, than a hypotonic solution.

Is sugar solution hypertonic or hypotonic?

Sugar solution is hypertonic solution. Hope this information will clear your doubts about the topic.

Will a cell shrink in a hypotonic solution?

Cells shrink in hypotonic solutions and swell in hypertonic solutions.

Is salt water hypotonic or hypertonic?

For example, a solution containing 10% salt is hypertonic. When a cell is placed in a hypertonic environment, there is a net movement of water to the outside of the cell (from the higher water environment inside the cell). The cell shrinks in response. A solution of low solute concentration is referred to as hypotonic.

What is an example of isotonic?

Common examples of isotonic solutions are 0.9% normal saline and lactated ringers. These fluids are useful when the patient has lost fluid volume from blood loss, trauma, or dehydration due to excessive nausea/vomiting or diarrhea.

Which of the following solution is hypotonic?


What happens to red blood cells in a hypertonic solution?

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 cellis placed in a hypotonic solution, the blood cell grows in size.

How do you remember hypertonic and hypotonic?

  1. Hypertonic fluids are for skinny cells because the fluid goes out of the cell, making it skinny.
  2. Hypotonic fluids can be considered hippotonic cells because all the fluid goes into the cell causing it to swell.

When can a solution be called hypotonic solution?

If the solution in the surrounding has a lower solute concentration as compared to the solute concentration inside the cell, then the solution is called hypotonic. Or, if the surrounding solution has high solvent concentration compared to the inside of the cell, then it is hypotonic solution.
