Diffusion is the spreading of a substance in another substance effected by the thermal movements of the molecules or other forces acting between the molecules. The spreading happens from an area with high density into areas with originally lower density.
For osmosis to occur you must have a solvent in two rooms separated by a membran that lets the solvent molecules pass. In one of the rooms there is a dissolved substance that cannot pass the membrane in a higher concentration than in the other room.
This makes solvent pass over to the room with the highest concentration of the substance so that the pressure gets higher in that room and the solution gets less concentrated. The process stops when the pressure is high enough or the concentration of the dissolved substance is equal in both rooms.
The mechanism behind osmosis is as follows: The solvent molecules are always moving because of their termal kinetic energy and are steadily colliding with each other and also with molecules of the dissolved substance. All the time some solvent molecules pass through the membran between the two rooms also, and in both directions.
But the dissolved substance will all the time collide with some of the solvent molecules and block their passage through the membran. Solvent molecules in the room with most dissolved substance will however be blocked more often from passing than solvent molecules in the other room. Thus there will be most passings from the room with the least dissolved substance.

5 differences between diffusion and osmosis?
The differences between diffusion and osmosis are really just that osmosis takes place with water and through a membrane. Diffusion is just the spread of molecules from high concentration to low. Osmosis is diffusion of water through a membrane.
What is a catchy title for osmosis and diffusion?
"Flowing Through Membranes: Osmosis and Diffusion Explained"
Distinguish between osmosis and diffusion?
The difference between Diffusion and Osmosis is by the process of them diffusing and the outcome such as an example of a sugar cube... In Diffusion Molecules move from high concentration just Osmosis although in the diffusion process of "Diffusion" it uses Kinetic energy and Concentration Gradient while "Osmosis" does not require cells to expand energy, in result Osmosis uses Passive Transport of Water.
What is the difffrence between diffusion and osmosis?
1 diff. Semi permiable membrane is required in osmosis while it is not required in diffusion. 2 diff. Osmosis cn occur only in liquid medium while diffusion cn occur in all mediums.
What is relationship between osmosis and diffusion?
The relationship is that osmosis is the diffusion of water throught a selective permeable membrane.
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
What is a synonym for osmosis?
assimilation , diffusion , passage
What is driven by hydrostatic fluid pressure?
Diffusion, Osmosis
What type are osmosis and diffusion?

The difference between osmosis and diffusion is that osmosis is the spreading of water from a high to low concentration while diffusion is the spreading of molecules or particles from a high to low co?
The key difference between osmosis and diffusion is that osmosis specifically refers to the movement of water across a semi-permeable membrane, while diffusion is the movement of molecules or particles from an area of higher concentration to an area of lower concentration. Osmosis involves the movement of only water molecules, while diffusion can involve any type of molecule or particle.

How is osmosis realted to diffusion?
Osmosis is related to diffusion by having something diffuse through a solvent
