How do plant cells control turgor pressure
WebPositive pressure inside cells is contained by the cell wall, producing turgor pressure. Pressure potentials are typically around 0.6–0.8 MPa, but can reach as high as 1.5 MPa in a well-watered plant. A Ψ p of 1.5 MPa equates to 210 pounds per square inch (1.5 MPa x 140 lb in-2 MPa-1 = 210 lb/in-2). As a comparison, most automobile tires are ... WebSep 5, 2024 · The turgor pressure definition in biology refers to the pressure that a fluid (such as water) exerts against the cell wall. Hydrostatic pressure is another name for it. The density of the liquid, the acceleration of gravity, and the depth of the fluid column may all be used to calculate the pressure in a liquid at rest.
