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 the movement of a solvent across a semipermeable membrane toward a higher concentration of solute. In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases.

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 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.
Osmosis refers to the movement of water molecules only. The slideshow shows an example of osmosis showing the direction of movement of water between two different concentrations of sugar...
Oct 1, 2020 · 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 is a process where water molecules move from an area of low solute concentration to high solute concentration through a semipermeable membrane. This movement can be influenced by factors like solute size and charge.
Feb 17, 2023 · Osmosis is defined as the spontaneous movement of solvent molecules from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane in order to equalize their concentrations on both sides of the membrane. What Causes Osmosis and Why does it Occur.
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.
