Question

difference between osmosis and diffusion

Answer 1

Hope it helps.............

Answer 2

Diffusion :-
1.It is the movement of all types of substances from the area of their higher free energy to the area of their lower free energy.
2.Diffusion can operate in ay medium.
3.Diffusion is applicable to all types of substances: solids, liquids or gases
4.It does not require any semipermeable membrane.
5.Turgor pressure or Hydrostatic pressure does not normally operate in diffusion.
But
Osmosis :-
1.It is the movement of only solvent or water from its higher free energy or chemical potential to the area of its lower chemical potential when the solute particles are not allowed to diffuse.
2.Osmosis operates only in a liquid medium.
3.It is applicable to only solvent part of a solution.
4.A semipermeable membrane is a must for the operation  of osmosis.
5.It is dependent upon the number of particles of other substances dissolved in liquid.
