Question

write th diffrence between osmosis and diffusion

Answer 1

✴Diffusion:-

[1] It is the movement of molecules are particles.
[2] It can occurs in liquid and gaseous medium.
[3] Semipermeable membrane is not required.

✴Osmosis:-

[1] It is the movement of water molecules.
[2] It occurs only in aqueous medium.
[3] Semipermeable membrane is required.

Answer 2

◆◆-----for Osmosis...
●●------for diffusion

◆◆Osmosis-Osmosis is a special type of diffusion, where the movement of solvent molecules from low concentration of solution to higher takes place, when they are separated by semipermeable membrane.

●●Diffusion is the net downward movement of a given substance (ions, atoms or molecules, etc.) along the free energy gradient from the place of its higher concentration to an area of its lesser concentration

◆◆.The osmosis occurs in liquid medium and only the solvent molecules move from one place to another

●●.The diffusion may occur in any medium and the diffusing particles may be solid, liquid or gas

◆◆.Semipermeable membrane is required

●●.Semipermeable membrane is not required.
