Dehydration Effect on the Internal Cell Pressure

Section: Soft matter
Original Author's Text: Ukrainian

Abstract: The dependence of the turgor pressure on the water content in a cellular structure is studied experimentally. The turgor pressure is found to decrease as the water content in a cell diminished. The experimental result is analyzed in the framework of a two-component cell model. The cell wall deformation is demonstrated to make a main contribution to the turgor pressure, so that a drop of the turgor pressure is a consequence of the stress relaxation in the cell wall.

Key words: deformation, stress relaxation, cell, turgor pressure.
