Diffusion is the tendency of particles in a gas or liquid to become evenly distributed by moving from areas of greater concentration to areas of lesser concentration. Diffusion is driven by the kinetic energy of particles that is a consequence of temperature. It is an inherently random process and particles continue to spread out until they are evenly distributed within the enclosed area.
Biologically, diffusion is the cause of random movement or net movement of particles from an area of high concentration towards an area of low concentration. Osmosis refers to the flow of particles across a membrane. When active transport is absent, diffusion provides the driving force for osmosis across a fully permeable or partially permeable membrane.
Fully permeable: all particles can move through.
Partially permeable: only certain particles an move through.
Active transport: biochemical processes expend energy to move particles.
Note: Reverse osmosis is basically filtering. Pressure is greater on one side of a partially permeable membrane pushing particles through it.

Is diffusion the same thing as Osmosis?
No, diffusion is the movement of molecules from an area of high concentration to low concentration, while osmosis is the specific type of diffusion involving water molecules moving across a semi-permeable membrane. Osmosis specifically refers to the movement of water molecules.
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 the diffusion of water molecules called?
The diffusion of water molecules is called osmosis. This process involves the movement of water across a selectively permeable membrane from an area of higher concentration to an area of lower concentration.
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.

How is osmosis realted to diffusion?
Osmosis is related to diffusion by having something diffuse through a solvent
Why is osmosis often thought to be a special type of diffusion?
Osmosis only works BECAUSE OF diffusion.
What life function is directly related to diffusion and osmosis?
Digestions is a life function that is directly related to diffusion and osmosis. The nutrients digested are absorbed and distributed via diffusion and osmosis.
