The meaning of OSMOSIS is movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane. How to use osmosis in a sentence.
Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes). The process, important in biology, was first thoroughly studied in 1877 by a German plant physiologist, Wilhelm Pfeffer.
Osmosis is when a substance crosses a semipermeable membrane in order to balance the concentrations of another substance. In biology, this is usually when a solvent such as water flows into or out of a cell depending on the concentration of a solute such as salt.
Osmosis provides the primary means by which water is transported into and out of cells. The turgor pressure of a cell is largely maintained by osmosis across the cell membrane between the cell interior and its relatively hypotonic environment.
the process in plants and animals by which a liquid moves gradually from one part of the body or the plant to another through a membrane (= cell covering): Fluid flows back into the tiny blood vessels by osmosis.

Osmosis is the net movement of solvent molecules through a semipermeable membrane. It is similar to diffusion as the movement is downhill , meaning from higher to lower concentration. In osmosis though, the movement has to occur across a semipermeable or selectively-permeable membrane .
Osmosis is the transfer of solvent from a region of lower concentration to a region of higher concentration. Explore more about the definition of osmosis and osmotic pressure.
noun. Physical Chemistry, Cell Biology. the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane. the diffusion of fluids through membranes or porous partitions.

Osmosis is the process where solvent molecules move through a semipermeable membrane from a dilute solution into a more concentrated solution (which becomes more dilute). In most cases, the solvent is water. However, the solvent may be another liquid or even a gas. Osmosis can be made to do work.
