turg
Turg, in informal or shorthand usage, refers to turgor pressure in plant cells. The formal term is turgor pressure (also called turgidity), the hydrostatic pressure exerted by the cell contents against the cell wall. The concept arises from water uptake by the cell’s vacuole through osmosis, which pushes the plasma membrane and cytoplasm against the rigid cell wall. In most scientific texts, the term “turg” is not standard, and researchers typically write “turgor” or “turgor pressure.”
Mechanism and role. Turgor pressure results from water inside the cytoplasm and vacuole pressing outward on
Measurement and typical values. Turgor is often discussed qualitatively in many contexts, but it can be measured
Related concepts. Turgor is balanced by cell wall tension and is opposed when water is lost, leading
