Difference Between Diffusion and Osmosis

Diffusion:

Diffusion is the movement of particles from the area of ​​highest concentration to the lowest concentration.

It is a passive process.

• Any kind of substance goes from the higher energy or concentration zone to the lower energy zone.
• Diffusion can occur in any medium (solid, liquid or gaseous).
• A semi-permeable membrane is not necessary for its diffusion.
• Diffusion is not based on pressure potential, solute potential.
• Diffusion mostly depends on the presence of different particles.

Osmosis:

Osmosis is the movement of solvent particles over a semi-penetrable membrane into a concentrated solution from a dilute solution.

• Osmosis is also a passive process.
• Only water or any other solvent circulates from the zone of high concentration to the zone of low concentration.
• Osmosis only occurs in the liquid medium.
• A semi-permeable membrane is necessary for osmosis.
• Osmosis depends on the potential of the solute.
• Osmosis is highly dependent on the number of solute particles that dissolve in the solvent.
