Question

Differentiate between the following pair on the basis of what is mentioned with bracket.

Diffusion and osmosis (definition)

Answer 1

Diffusion:

Diffusion is the means of transport through the free movement of molecules from a region of higher concentration to a region of lower concentration.

Osmosis:

Osmosis is a type of diffusion of solvent molecules across a semipermeable membrane from a region of higher solvent concentration toward a region of lower solvent concentration.

Diffusion	Osmosis
1. Diffusion involves the movement of both solute and solvent molecules to maintain equilibrium.	1. Osmosis involves the movement of only solvent molecules to maintain an equilibrium.
2. It does not involve the passage of molecules through a semipermeable membrane.	2. It involves the movement of solvent molecules across a semipermeable membrane.
3. It occurs in all mediums.	3. It takes place only in a liquid medium.
4. The flow of molecules can occur in all directions.	4. The flow of molecules occurs only in one direction.
