Difference between Diffusion and Osmosis

Here are some points mentioned that show the difference between diffusion and osmosis.
Diffusion: Diffusion is the particle movement from the higher concentration area to the lower concentration.
It is a passive process.
  • Any kind of substance goes from the area of the highest energy or from the concentration to the lowest energy area.
  • The diffusion can be occurring in every medium (solid, liquid or gas).
  • A semi-permeable membrane is not required for diffusion.
  • Diffusion does not rely on the pressure potential, solute potential.
  • Diffusion for the mostly relies upon the presence of different particles.

Osmosis: Osmosis is the solvent particle movement over a membrane of semi penetrable into a concentrated solution from a dilute solution.
  • Osmosis is also a passive process.
  • Just the water or any other solvent are traveling from the area of high concentration to the area of low concentration.
  • Osmosis happens just in the liquid medium.
  • A semi-permeable membrane is required for osmosis.
  • Osmosis relies on the potential of solute.
  • Osmosis depends largely on the number of solute particles which dissolves in the solvent.
