	Elongation growth and turgor pressure of stage IVb sporangiophores of Phycomyces blakesleeanus during anoxia
		In this study, elongation growth and turgor pressure of the stalk were measured during anoxia (the atmospheric air is replaced with nitrogen gas in a chamber containing the growing sporangiophore).
		Turgor pressure measurements with the pressure probe demonstrate that an immediate and sharp decrease in turgor pressure occurs when the oxygen concentration is reduced from 21% to less than 1%.
		In other cases, the subsequent decrease in turgor pressure is gradual for a period of time before it begins decreasing exponentially.

		The force per unit area required to prevent the passage of solvent through a selectively-permeable membrane and into a solution of greater concentration is equivalent to the turgor pressure.
		Osmotic pressure is a colligative property, meaning that the property depends on the concentration of the solute but not on its identity.
		The force per unit area, or pressure, required to prevent the passage of water through a selectively-permeable membrane and into a solution of greater concentration is equivalent to the osmotic pressure of the solution, or turgor.

		An everyday analogy of how turgor pressure works is when you have two dinner plates stacked up on one another and there is dishwater in between the two surfaces.
		The thin layer of water creates outward pressure so the two plates are actually not resting directly on one another; rather they are separated by the thin layer of water that exerts an outward pressure against the surface of the plates.
		In the abdominal and thoracic cavities, this pressure system exists because the cavities are pressurized systems, meaning that they are closed off from air moving freely in and out of the cavities.

		It depends on psi = water potential, delta P = hydrostatic pressure, sigma = the ratio of the apparent osmotic pressure to the theoretical osmotic pressure for the semipermeable membrane and pi = osmotic pressure of the compartment (cell).
		As long as the cells are still living can the turgor pressure be fixed again, a phenomenon common in everyday life: wilted plants recover after watering.
		Osmosis and turgor pressure have been extensively examined at the end of the last century by W.

		Inadequate sodium transport out of the kidneys, because of a mutant sodium channel, leads to elevated osmotic pressure of the blood and resulting hypertension (high blood pressure).
		When the turgor pressure equals the osmotic pressure, osmosis ceases.

		A fringe of stiff hairs around the edge of the blade become interlocked (intermeshed) when the blade folds closed, thus trapping the insect like bars in a jail cell.
		The action of this remarkable mechanism involves a rapid loss of turgor pressure within the leaf cells on the upper side of the leaf.
		As a result, a partial vacuum is produced inside the bladder and the pressure on the outside becomes greater than inside.

		(Redirected from Turgor) Turgor (also called turgor pressure or osmotic pressure) is the pressure produced in a space that is enclosed by a semipermeable membrane.

		Pressure cooking (ie: autoclaving) will sterilize the soil for sure.
		In the presence of these round- worms, the fungal hyphae produce loops that swell rapidly, closing the opening like a noose when a nematode rubs against its inner surface.
		Presumably the stimulation of the cell wall increases the amount of os- motically active material in the cell, caus- ing water to enter the cells and increase their turgor pressure.
