Question

How would you explain the process of diffusion and osmosis?

Answer 1

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

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.
