due to inward diffusion
it is also called "hydrostatic pressure", and defined as the pressure measured by a fluid, measured at a certain point within itself when at equilibrium. 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. this system is not seen in animal cells, seeing how the absence of a cell wall would cause the cell to lyse when under too much pressure. 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. osmotic flow of water through a semipermeable membrane is when the water travels from an area with a low-solute concentration, to one with a higher-solute concentration. in plants, this entails the water moving from the low concentration solute outside the cell, into the cell's vacuole.
turgor pressure
a plant cell in hypotonic solution will absorb water by endosmosis, so that the increased volume of water in the cell will increase pressure, making the protoplasm push against the cell wall, a condition known as turgor. turgor makes plant cells push against each other in the same way and is the main line method of support in non-woody plant tissue. plant cell walls resist further water entry after a certain point, known as full turgor, which stops plant cells from bursting as animal cells do in the same conditions. this is also the reason that plants stand upright. without the stiffness of the plant cells the plant would fall under its own weight. turgor pressure allows plants to stay firm and erect, and plants without turgor pressure (known as flaccid) wilt. a cell will begin to decline in turgor pressure only when there is no air spaces surrounding it and eventually leads to a greater osmotic pressure than that of the cell. vacuoles play a role in turgor pressure when water leaves the cell due to hyperosmotic solutions containing solutes such as mannitol, sorbitol, and sucrose.
