'''Turgor basıncı''' ya da '''turgor''', [[bitki]] hücrelerinin [[saf su]]ya konmasıyla içine su alarak, şişmesi ve hücrenin çeperine [[basınç]] yapması olayına denir.

Turgor basıncı, suyun içeri girişine engel olmaya çalışan bir kuvvettir.

In [[biology]], '''turgor pressure''' or turgidity is the pressure of the [[cell (biology)|cell]] contents against the [[cell wall]], in [[plant cell]]s, determined by the water content of the [[vacuole]], resulting from [[osmotic pressure]]. i.e. the [[hydrostatic pressure]] produced by a solution in a space divided by a [[semipermeable membrane]] due to a differential in the concentration of solute. Turgid plant cells contain more water than flaccid cells and exert a greater osmotic pressure on its cell walls.
When a [[cell (biology)|cell]] is in a [[hypotonic]] environment, water flows across the [[cell membrane]] into the cell, causing it to expand due to osmotic pressure. In [[plant cell]]s, [[water]] enters the cell until the inside and outside water potential is equal, however, the [[cell wall]] prevents the cell from bursting, resulting in pressure on the cell wall from within.
The pressure of each cell wall against its neighbor results in stiffness that allows the plant to stay upright. Cells not adapted to hypo tonic environments will burst due to the inflow of water if they have no strong membrane or cell wall.
The opposite condition in a plant cell, resulting from immersion in a [[hypertonic]] environment, is [[plasmolysis]].
Turgor pressure is not only important in terms of plant rigidity, but also of key importance in microbial growth.
