Tonicity: Definition, Types, and Examples - Science Facts
WEBFeb 2, 2023 — Tonicity is the extracellular solution’s ability to make water move inside or outside the cell by the process of osmosis. It measures the amount of solute dissolved in a specific amount of the solution, also known as the solution’s osmolarity.
Tonicity - Definition and Quiz - Biology Dictionary
WEBApr 28, 2017 — Tonicity is the concentration of a solution as compared to another solution. Concentration describes the amount of solutes dissolved by a solution. If a solution has a higher concentration of solutes (less water) than …

Tonicity - Wikipedia
WEBIn chemical biology, tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a partially-permeable cell membrane. Tonicity depends on the relative concentration of selective membrane-impermeable solutes across a cell membrane which determine the direction and extent of osmotic flux .
Biochemistry, Hypertonicity - StatPearls - NCBI Bookshelf
WEBAug 8, 2023 — Tonicity is the capability of a solution to modify the volume of cells by altering their water content. The movement of water into a cell can lead to hypotonicity or hypertonicity when water moves out of the cell.
3.3C: Tonicity - Medicine LibreTexts
WEBJan 17, 2023 — Tonicity describes how an extracellular solution can change the volume of a cell by affecting osmosis. A solution’s tonicity often directly correlates with the osmolarity of the solution. Osmolarity describes the total solute concentration of the solution.
Tonicity - Definition, Types, Examples - Biology Notes Online
WEBApr 2, 2024 — Tonicity refers to the ability of an extracellular solution to move water inside or outside a cell through the process called osmosis. It is also known as the solution’s osmolarity, which measures how much solute has been dissolved in a …
4.6: Osmosis and Tonicity - Biology LibreTexts
WEBThe relative concentration of solutes on the outside of the cell is the solution’s tonicity. There are three terms we can use to describe the tonicity of the cell’s environment. Isotonic: The solute concentration outside the cell is equal to the solute concentration on the inside.
6.5: Passive Transport - Osmosis - Biology LibreTexts
WEBTonicity. Tonicity describes the amount of solute in a solution. The measure of the tonicity of a solution, or the total amount of solutes dissolved in a specific amount of solution, is called its osmolarity. Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular ...

WEBCells react differently in hypotonic, isotonic, and hypertonic solutions. In a hypotonic solution, water rushes into the cell causing it to expand or even burst. In an isotonic solution, there is no net flow of water, keeping the cell stable. In a hypertonic solution, water leaves the cell, causing it to shrivel. These reactions are due to the semipermeable …
