What is the biology term of isotonic?

Answer 1

If you're asking about what the term isotonic means...there are three basic types of solutions- Hypertonic, Hypotonic and Isotonic

Hypertonic Solutions are solutions that contain more solute than the other solution in question.

Hypotonic solutions are less concentrated with solute than the other solution

(When i refer to the "other solution" usually when you talk about isotonic solutions etc, you are talking about it in reference to another solution)

Isotonic solutions are solutions that contain an EQUAL amount of solute with the other solution and the solute diffuses equally from one solution to the other...

SOrry if anything is innaccurate, but a proper definition (other than mine) shouldn't be hard to get once you understand this...

Answer 2

Isotonic solution: A solution that has the same solute concentration as the cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients. when a cell is in a isotonic environment , it means the the amount (concentration) of the solutes in the solution and the amount (concentrarion) of solutes in the cell itself is Equal.

So both the solution and Cell have EQUAL amount or Equal concentration of SOLUTES (like salt, sugar, Na+ etc) .

Example

If the cell has 50% salt or any solutes

and you place the cell in a solution that has 50% salt or any solutes

then you can say that the cell is in Isotonic Environment. There will be no change in cell's shape.

But if cell has 30% salt and you place the cell in a solution that has 70% salt

then the cell is in Hypertonic solution. Then the water will move out of cell into solution to achieve equilibrium through osmosis. the cell will shrink.

And If the cell has 80% salt and you place the cell in a solution that has 20% salt then the cell is in Hypotonic solution. Then water will move out of solution and come into cell through osmosis to achieve equilbrium and the cell will swell( cell will be come bigger) .

Answer 3

Isotonic refers to a solution that has the same concentration of solutes as another solution. In Biology, isotonic solutions have equal concentrations of solutes inside and outside of a cell, resulting in no net movement of water across the cell membrane. This allows for a stable environment for cells.
