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 a hypotonic solution in biology?

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

What is a hypotonic solution Class 9?

(ii) Hypotonic solution: A solution having a lesser concentration of solute inside as compared to outside the cell is called a hypotonic solution.

What is hypotonic solution and examples?

A hypotonic solution is a solution that has a lower concentration of solute compared to the cell. Solutions are mixtures composed of a solute and a solvent. 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.

What is hypertonic solution example?

A hypertonic solution is one which has a higher solute concentration than another solution. An example of a hypertonic solution is the interior of a red blood cell compared with the solute concentration of fresh water.

What is a hypertonic solution in biology?

A hypertonic solution is any external solution that has a high solute concentration and low water concentration compared to body fluids. In a hypertonic solution, the net movement of water will be out of the body and into the solution.

What means isotonic?

Definition of isotonic

1 : of, relating to, or being muscular contraction in the absence of significant resistance, with marked shortening of muscle fibers, and without great increase in muscle tone — compare isometric. 2 : isosmotic —used of solutions.

What are the types of hypotonic solution?

Hypotonic solutions
  • 0.45% Saline (1/2 NS)
  • 0.225% Saline (1/4 NS)
  • 0.33% saline (1/3 NS)

What are hypertonic fluids?

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 is hypotonic solution quizlet?

What is a hypotonic solution? The solution has a lower solute concentration than the cell so water moves into the cell causing plant cells to swell and animal cells to swell and burst.

What does hypotonic mean in osmosis?

Osmosis is the diffusion of water. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower concentration is hypotonic.

Does hypotonic shrink or swell?

A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink. A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.

What is isotonic solution in biology?

Isotonic solutions contain equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks.

Is pure water hypotonic?

Compared to any cell, pure water is hypotonic. In hypotonic solution there is less number of solute particles and more water. thus, it generates less osmotic pressure. That’s why pure water is hypotonic.

How do you remember hypertonic and hypotonic?

Hypertonic and hypotonic are not the same.

If a cell is put into a hypertonic solution, water will leave the cell. A quick tip to remembering this is to visualize “hyper” kids who want to go play outside! In contrast, when a cell is put into a hypotonic solution, water will enter the cell.

How do you make a hypotonic solution?

A common preparation is made by mixing a stock solution of 23.4% hypertonic saline with 6% hetastarch or pentastarch in a 1 : 2 ratio to arrive at a total volume of 3 to 5 ml/kg.

Is salt water hypotonic?

A solution containing 0.5% salt is hypotonic with respect to the cell. When a cell is placed in a hypotonic environment, there is a net movement of water into the cell. The cell swells in response.

Is Sugar hypertonic or hypotonic?

Sugar solution is hypertonic solution.
