Higher turgor pressure

Web6 de abr. de 2024 · In plants, turgor is also known as hydrostatic pressure or water potential or turgor pressure. Hydrostatic pressure is the force within the cell that pushes the plasma membrane against the cell wall. It is a kind of pressure which is produced due to water. It occurs only in a plant cell..

WebMore recent measurements indicate a turgor pressure for E. coli as low as ∼ 0.3 atm (primary source Deng et al., 2011). The higher turgor of Gram-positive bacteria must reflect a higher osmolyte concentration (e.g. K+ and counter ions) and consequently it will take a larger osmotic upshift to plasmolyse Gram-positive bacteria than Gram-negative cells.
