What Is Turgor Pressure in Plant Cells?

Turgor pressure is the pressure of water against the inside wall of a plant cell. It causes plant cells to remain turgid, enabling the plant to stand upright without wilting.

An influx of water occurs when ions, sugars or other solutes are stored in a plant's vacuole. This process occurs in plants, bacteria, fungi and protists that contain cell walls. Osmosis, the tendency for water to flow from an area of low solute concentration to an area of high solute concentration, occurs when a cell's vacuole has a higher solute concentration than the surrounding cytoplasm due to the presence of solutes in the vacuole.
