Turgor pressure 4414104 223121291 2008-07-02T17:45:45Z Filll 2379776 this needs work {{Refimprove|date=July 2006}} ''''Turgor pressure'''' or turgidity is the main pressure of the [[cell (biology)|cell]] contents against the [[cell wall]] in [[plant cell]]s and bacteria cells, 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. Turgor is a force exerted outward on a plant cell wall by the H<sub>2</sub>O contained in the cell. This force gives the plant rigidity, and may help to keep it erect. Turgor may also result in the bursting of a cell. ==See also== *[[Cell wall]] *[[Osmotic pressure]] *[[Osmosis]] ==External links== * [http://www.biologie.uni-hamburg.de/b-online/e22/22c.htm Osmotic pressure] * [http://www.microscopy-uk.org.uk/mag/artoct99/plantupright.html How do non woody plants stay upright?] * [http://lsvr12.kanti-frauenfeld.ch/KOJ/Java/Osmosis.html NetLogo Turgor simulation for educational use (Java Applet for fast PCs)] * [http://lsvr12.kanti-frauenfeld.ch/KOJ/Java/Osmosis_fast.html NetLogo Turgor simulation for educational use (Java Applet, runs fast also on slow PCs)] <ref>mudau k:2008;biology for life sciences, uwc</ref> ==References== <references /> Campbell, N.
