Hydrostatic force in plants, fungi and also walled bacteria and protists
Look up turgid in Wiktionary, the free dictionary.
Turgor pressure is the force within the cell that pushes the plasma membrane against the cell wall.[1]
It is also called hydrostatic pressure, and is defined as the pressure in a fluid measured at a certain point within itself when at equilibrium.[2] Generally, turgor pressure is caused by the osmotic flow of water and occurs in plants, fungi, and bacteria. The phenomenon is also observed in protists that have cell walls.[3] This system is not seen in animal cells, as the absence of a cell wall would cause the cell to lyse when under too much pressure.[4] The pressure exerted by the osmotic flow of water is called turgidity. It is caused by the osmotic flow of water through a selectively permeable membrane. Movement of water through a semipermeable membrane from a volume with a low solute concentration to one with a higher solute concentration is called osmotic flow. In plants, this entails the water moving from the low concentration solute outside the cell into the cell's vacuole.[citation needed]
