Turgor pressure

Definition

noun

The pressure exerted by water inside the cell against the cell wall.


Supplement

When a plant cell stores ions, sugars and other solutes in its vacuole, this causes an influx of water. The influx of water results in a large turgor pressure exerted on the plant cell wall. This makes plant cells to become turgid, thus, helping the plants to stand upright, and do not wilt.

See also: turgidity, osmotic pressure.
