  2. Tonicity - Wikipedia

    en.wikipedia.org/wiki/Tonicity

    A hypertonic solution has a greater concentration of non-permeating solutes than another solution. [2] 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 ...

  3. Plasmolysis - Wikipedia

    en.wikipedia.org/wiki/Plasmolysis

    Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

  4. Cytolysis - Wikipedia

    en.wikipedia.org/wiki/Cytolysis

    Blood cells in solutions with different osmotic pressure. Cytolysis would result in the image on the far right. Micrographs of osmotic pressure on red blood cells A human white blood cell (upper right) in water swells until it bursts (at ~14 seconds)

  5. Crenation - Wikipedia

    en.wikipedia.org/wiki/Crenation

    The descriptor can apply to objects of different types, including cells, where one mechanism of crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis.

  6. Turgor pressure - Wikipedia

    en.wikipedia.org/wiki/Turgor_pressure

    When in a hypotonic solution, water flows into the membrane and increases the cell's volume, while in an isotonic solution, water flows in and out of the cell at an equal rate. [ 4 ] Turgidity is the point at which the cell's membrane pushes against the cell wall, which is when turgor pressure is high.

  7. Osmotic shock - Wikipedia

    en.wikipedia.org/wiki/Osmotic_shock

    In hypertonic solutions water flows out of the cell and the cell shrinks (plasmolysis). In hypotonic solutions, water flows into the cell and the cell swells ( turgescence ). Osmotic shock or osmotic stress is physiologic dysfunction caused by a sudden change in the solute concentration around a cell , which causes a rapid change in the ...

  8. Osmosis - Wikipedia

    en.wikipedia.org/wiki/Osmosis

    The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...

  9. Hemolysis - Wikipedia

    en.wikipedia.org/wiki/Hemolysis

    A red blood cell in a hypotonic solution, causing water to move into the cell A red blood cell in a hypertonic solution, causing water to move out of the cell. Hemolysis or haemolysis (/ h iː ˈ m ɒ l ɪ s ɪ s /), [1] also known by several other names, is the rupturing of red blood cells (erythrocytes) and the release of their contents into surrounding fluid (e.g. blood plasma).
