Osmosis Definition & Meaning - Merriam-Webster
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 …
Osmosis | Definition, Examples, & Facts | Britannica
2024年9月10日 · 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 - Definition and Examples - Biology Dictionary
2020年10月1日 · 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 - Wikipedia
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.
OSMOSIS | English meaning - Cambridge Dictionary
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 …
Osmosis: Video, Causes, & Meaning | Osmosis
Well, 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.
What Is Osmosis? - Definition, Types, Osmotic Pressure - BYJU'S
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 - Definition and Examples - Biology Online Dictionary
2023年8月25日 · 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: Definition and How Does it Occur (with Diagram)
2023年2月17日 · 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.
Osmosis Definition in Chemistry and Biology - ThoughtCo
2019年7月3日 · 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.
