Hint: Diffusion is referred to as the movement of any substance from a region of its higher concentration to a region of lower concentration. It takes place in all directions. Osmosis is referred to as the movement of water or any other solvent from a region of low solute concentration to a region of high solute concentration. It is a kind of unidirectional phenomenon.
Complete answer:
Now let us explain the process of diffusion and osmosis
Note: Diffusion does now not require a semipermeable membrane whilst osmosis does require. When osmosis is a unidirectional phenomenon; the diffusion occurs in all directions. Further, in osmosis, the solely solvent flows whilst in diffusion, all materials move.

Diffusion | Osmosis |
Diffusion is referred to as the movement of any substance from a region of its higher concentration to a region of lower concentration. | Osmosis is referred to as the movement of water or any other solvent from a region of low solute concentration to a region of high solute concentration. |
It takes place in liquids and gases | It takes place in liquids only |
It do not requires any membrane separation | It requires the semipermeable membrane |
It can takes place in every direction | It takes place only in one direction. |
It is a natural phenomenon that can not be reversed or stopped | It can be reversed or can be stopped by applying force |
Water is not necessary for diffusion to occur | Water is necessary for osmosis to occur. |
Example includes :- addition of ink in water leads to change of colour of water | Example :- swelling of red blood cells. |
Note: Diffusion does now not require a semipermeable membrane whilst osmosis does require. When osmosis is a unidirectional phenomenon; the diffusion occurs in all directions. Further, in osmosis, the solely solvent flows whilst in diffusion, all materials move.
