Osmosis: Video, Anatomy, Definition & Function | Osmosis
WebWell, then, simply put, osmosis is how water molecules move across a semipermeable membrane that separates two solutions. It can be thought of as passive diffusion of water and it requires no energy. When water molecules move like this, they end up equalizing the concentrations of the solutions on either side of the membrane.
Osmosis | Definition, Examples, & Facts | Britannica
Webosmosis, 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 - Wikipedia
WebOsmosis 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.
Osmosis: what is osmosis? (video) | Khan Academy
WebOsmosis is a fascinating process where water molecules move from an area of low solute concentration to an area of high solute concentration through a semipermeable membrane. This movement can be due to mechanical blockage by larger solute particles or the water molecules being attracted to charged solute particles.
Osmosis - Definition and Examples | Biology Dictionary
WebOct 1, 2020 · Osmosis Definition. Osmosis is a type of diffusion that, in biology, is usually related to cells. Diffusion is when molecules or atoms move from an area of high concentration to an area of low concentration. Osmosis is when a substance crosses a semipermeable membrane in order to balance the concentrations of another substance.
Osmosis and tonicity - Khan Academy
WebThe ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is a bit different from osmolarity because it takes into account both relative solute concentrations and the cell membrane’s permeability to those solutes.

WebJul 3, 2019 · 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 . Read More.
