Tonicity: hypertonic, isotonic & hypotonic solutions (article)
WebTonicity is a concern for all living things, particularly those that lack rigid cell walls and live in hyper- or hypotonic environments. For example, paramecia—pictured below—and amoebas, which are protists that lack cell walls, may have specialized structures called contractile vacuoles.
Hypotonic Solution - Definition & Examples | Biology Dictionary
WebOct 4, 2019 · A hypotonic solution is a solution that has a lower solute concentration compared to another solution. A solution cannot be hypotonic, isotonic or hypertonic without a solution for comparison. Hypotonic is a description of the solute content of one solution in relation to another solution.
Hypotonic, isotonic, and hypertonic solutions (tonicity) - Khan Academy
WebHypoosmotic and hypotonic refer to solutions that have a lower solute concentration than the cell. In this case, water will move into the cell by osmosis, causing the cell to swell. Isoosmotic and isotonic refer to solutions that have the same solute concentration as …

WebA red blood cell in a hypotonic solution, causing water to move into the cell. 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 …
Hypertonic vs. Hypotonic Solutions: Differences and Uses
WebFeb 7, 2024 · Hypertonic solutions have a higher solute concentration and cause water to move out of cells, potentially leading to cell shrinkage. Hypotonic solutions, on the other hand, have a lower solute concentration and cause water to move into cells, potentially causing them to swell or burst.

WebAug 6, 2023 · 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.
Hypotonic - Definition and Examples | Biology Dictionary
WebApr 28, 2017 · Hypotonic can mean several things in biology. Its many definitions apply to both human biology and biochemistry. When referring to humans or animals, hypotonic signifies a muscle’s having less tone, or shape, compared to a normal comparison model or when compared to another muscle in the same human body. The biochemical fields take …
Hypotonic - Definition and Examples - Biology Online Dictionary
WebAug 25, 2023 · A hypotonic is a term used to describe something that has a lesser degree of tone, tension, or tonicity. At the cellular level, it describes a solution with a comparatively lower solute concentration than that in another solution being compared. It may also indicate a lower osmotic pressure.
