Osmosis is the spontaneous net movement of solvent molecules through a semi- permeable The turgor pressure of a cell is largely maintained by osmosis across the cell membrane between the cell interior and its relatively hypotonic. If a red blood cell is placed in water, water enters the cell by osmosis. Because the membrane is quite weak the cell will burst as the volume and therefore the.

Microinjection experiments with mRNA encoding aquaporin , an erythrocyte membrane protein , provided convincing evidence that this protein increases the permeability of cells to water Figure Osmosis is responsible for the ability of plant roots to draw water from the soil. The definition of osmosis is as follows:. As noted early in this chapter, most biological membranes are relatively impermeable to ions and other solutes, but like all phospholipid bilayers, they are somewhat permeable to water see Figure The etymology of the word "osmosis" is discussed in: Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. The specific problem is:

Osmosis can be demonstrated when potato slices are added to a high salt solution. Osmoregulation involving the kidneys ensures that the concentration of the blood stays about the same as the concentration of the cell contents. Trends in Plant Science. These observations led investigators to suspect that the plasma membranes of erythrocytes and other cell types contain water-channel proteins that accelerate the osmotic flow of water. As a result of these factors, in the absence of some countervailing mechanism, the cytosolic solute concentration would increase, causing an osmotic influx of water and eventually cell lysis.
