the diffusion of pure solvent across a membrane in response to a concentration gradient, usually from a solution of lesser to one of greater solute concentration. osmosis. (ŏzmō`sĭs), transfer of a liquid solvent through a semipermeable membrane that does not allow dissolved solids (solutes) to pass. Osmosis refers only. 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.

In either case the direction of transfer is from the area of higher concentration of the material transferred to the area of lower concentration. The membrane is impermeable to the solute but is permeable to the solvent. Osmosis was first observed by J. This means that the molecules of water moving in either direction are equal, so effectively there is no overall net movement of water. Continue Find out. One theory on aging holds that cells are preprogrammed to divide only a certain number of times kjijj they die. Finally, the cell ruptures, releasing its contents into the surrounding tissue.
