What is the difference between diffuse and osmosis?
Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely. Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed.
How do the forces that drive diffusion and osmosis differ?
Diffusion is a spontaneous movement of particles from an area of high concentration to an area of low concentration. Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient.
Is osmosis opposite to diffusion?
Osmosis is a special type of diffusion and can only be used to describe the movement of water molecules (as oppose to another type of molecule such as a gas). Osmosis occurs where there is a semi-permeable membrane which only allows water molecules through.
What are the two major differences between diffusion and osmosis?
Difference between Osmosis and Diffusion
| Osmosis | Diffusion |
|---|---|
| Only the solvent molecules can diffuse. | Both the molecules of solute and solvent can diffuse. |
| The flow of particles occurs only in one direction. | The flow of particles occurs in all the directions. |
Why is osmosis a special case of diffusion?
If the solute particles can’t cross a barrier, the only way to equalize concentration on both sides of the membrane is for the solvent particles to move in. You can consider osmosis to be a special case of diffusion in which diffusion occurs across a semipermeable membrane and only the water or other solvent moves.
What’s the difference between osmosis and Brownian motion?
Brownian motion: The random motion observed under a microscope as particles skip, slip, and dart within a liquid. Collective diffusion: The diffusion of a large number of particles within a liquid that remain intact or interacting with other particles. Osmosis: The diffusion of water through a cell membrane.
When does osmosis occur on a differential permeable membrane?
Osmosis will occur whenever the water concentrations are different on either side of a differentially permeable membrane. Osmosis can be defined as the movement of water molecules from a higher water concentration area to the area of less water concentration through a semipermeable membrane.
What is the difference between gaseous diffusion and facilitated diffusion?
Facilitated diffusion: Spontaneous passive transport of ions or molecules across a cell membrane (different because it happens outside the active phase of osmosis or intracellular diffusion). Gaseous diffusion: Used mainly with uranium hexafluoride to produce enriched uranium for nuclear reactors and weapons .
