  2. Plasmolysis - Wikipedia

    en.wikipedia.org/wiki/Plasmolysis

    If a plant cell is placed in a hypertonic solution, the plant cell loses water and hence turgor pressure by plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane and making the plant cell shrink and crumple.

  3. Tonicity - Wikipedia

    en.wikipedia.org/wiki/Tonicity

    When plant cells are in a hypertonic solution, the flexible cell membrane pulls away from the rigid cell wall, but remains joined to the cell wall at points called plasmodesmata. The cells often take on the appearance of a pincushion , and the plasmodesmata almost cease to function because they become constricted, a condition known as plasmolysis .

  4. Crenation - Wikipedia

    en.wikipedia.org/wiki/Crenation

    Plasmolysis is the term which describes plant cells when the cytoplasm shrinks from the cell wall in a hypertonic environment. In plasmolysis, the cell wall stays intact, but the plasma membrane shrinks and the chloroplasts of the plant cell concentrate in the center of the cell.

  5. Cytorrhysis - Wikipedia

    en.wikipedia.org/wiki/Cytorrhysis

    Cytorrhysis of plant cells can be induced in laboratory settings if they are placed in a hypertonic solution where the size of the solutes in the solution inhibit flow through the pores in the cell wall matrix.

  6. Turgor pressure - Wikipedia

    en.wikipedia.org/wiki/Turgor_pressure

    Along with size, rigidity of the cell is also caused by turgor pressure; a lower pressure results in a wilted cell or plant structure (i.e. leaf, stalk). One mechanism in plants that regulate turgor pressure is the cell's semipermeable membrane, which allows only some solutes to travel in and out of the cell, maintaining a minimum pressure.

  7. Osmosis - Wikipedia

    en.wikipedia.org/wiki/Osmosis

    Osmotic pressure is the main agent of support in many plants. The osmotic entry of water raises the turgor pressure exerted against the cell wall, until it equals the osmotic pressure, creating a steady state. [15] When a plant cell is placed in a solution that is hypertonic relative to the cytoplasm, water moves out of the cell and the cell ...

  8. 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 ...

  9. Contractile vacuole - Wikipedia

    en.wikipedia.org/wiki/Contractile_vacuole

    Species that possess a contractile vacuole typically always use the organelle, even at very hypertonic (high concentration of solutes) environments, since the cell tends to adjust its cytoplasm to become even more hyperosmotic than the environment.
