  • Tonicity: Definition, Types, and Examples - Science Facts
    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 - Wikipedia
    In biology, the tonicity of a solution usually refers to its solute concentration relative to that of another solution on the opposite side of a cell membrane; a solution outside of a cell is called hypertonic if it has a greater concentration of solutes than the cytosol inside the cell
  • Tonicity: hypertonic, isotonic hypotonic solutions (article) | Khan . . .
    The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity Tonicity is a bit different from osmolarity because it takes into account both relative solute concentrations and the cell membrane’s permeability to those solutes
  • Understanding Tonicity In Chemistry: Definition, Importance, And . . .
    Hypertonic, Hypotonic, Isotonic Solutions Tonicity describes the effective osmotic pressure of a solution relative to another, driven by solute concentration gradients across a semipermeable membrane In chemistry and biology, understanding tonicity is crucial for processes like cell volume regulation, drug delivery, and food preservation
  • Unravelling tonicity: Causes of confusion and pathways to clarity
    In this article, we aim to resolve the confusion surrounding tonicity in three steps We will first address and resolve the four superficial causes, then the three deep causes, and finally, we will illustrate the physical nature and three properties of tonicity
  • Osmosis, Tonicity, and Hydrostatic Pressure - Colorado State University
    Osmotic pressure is defined as the hydrostatic pressure required to stop the flow of water, and thus, osmotic and hydrostatic pressures are, for all intents and purposes, equivalent
  • 9. 10: Osmolarity and Tonicity - Biology LibreTexts
    Tonicity is the effective osmolality and is equal to the sum of the concentrations of the solutes which have the capacity to exert an osmotic force across the membrane The key parts are effective and capacity to exert The implication is that tonicity is less then osmolality How much less?
  • Tonicity - Definition, Types, Examples - Biology Notes Online
    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 given amount of solution
  • What is tonicity in biology? - California Learning Resource Network
    In biological systems, tonicity is a crucial concept related to osmosis and the movement of water across semi-permeable membranes It specifically describes the relative concentration of solutes in a solution compared to another solution, typically the intracellular fluid of a cell
