  2. Turgor pressure - Wikipedia

    en.wikipedia.org/wiki/Turgor_pressure

    Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth. 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 ...

    In biology, turgor pressure or turgidity is the pressure of the cell contents against the cell wall, in plant cells, determined by the water content of the vacuole, resulting from osmotic pressure.

  4. Plant cell - Wikipedia

    en.wikipedia.org/wiki/Plant_cell

    Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

  5. Plasmolysis - Wikipedia

    en.wikipedia.org/wiki/Plasmolysis

    A plant cell in hypotonic solution will absorb water by endosmosis, so that the increased volume of water in the cell will increase pressure, making the protoplasm push against the cell wall, a condition known as turgor. Turgor makes plant cells push against each other in the same way and is the main line method of support in non-woody plant ...

  6. Suction pressure - Wikipedia

    en.wikipedia.org/wiki/Suction_pressure

    When a plant cell is placed in a hypotonic solution, water enters into a cell by endosmosis and as a result turgor pressure (TP) develops in the cell. The cell membrane becomes stretched and the osmotic pressure (OP) of the cell decreases. As the cell absorbs more and more water its turgor pressure increases and osmotic pressure decreases.

  7. Wall stress relaxation - Wikipedia

    en.wikipedia.org/wiki/Wall_stress_relaxation

    Wall stress (measured in force per unit area) is created in response to the plant cell's turgor pressure. [2] Turgor pressure creates tension in the cell walls of plants, fungi, and bacteria, as it opposes the pressure of the cell's primary cell wall; this also allows for stretching of the cell wall. [1] The stretching of the cell wall, or the ...

  8. Cytorrhysis - Wikipedia

    en.wikipedia.org/wiki/Cytorrhysis

    Schematic of typical plant cell. Cytorrhysis is the permanent and irreparable damage to the cell wall after the complete collapse of a plant cell due to the loss of internal positive pressure (hydraulic turgor pressure). [1] Positive pressure within a plant cell is required to maintain the upright structure of the cell wall. [1]

  9. Wilting - Wikipedia

    en.wikipedia.org/wiki/Wilting

    This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. Wilting also serves to reduce water loss, as it makes the leaves expose less surface area. [1] The rate of loss of water from the plant is greater than the absorption of water in the plant.
