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.
