Diffusion and osmosis are two processes that involve the movement of molecules across a semi-permeable membrane. Both processes play an important role in living organisms, but they differ in terms of how substances move. In this article, we will discuss the differences between diffusion and osmosis.
Difference Between Diffusion And Osmosis
|Movement of particles from an area of higher concentration to lower concentration.
|Movement of water molecules from a low solute concentration to high solute concentration.
|Diffusion involves any type of particle, osmosis involves only water molecules.
|Diffusion is unidirectional, osmosis is bidirectional.
|Diffusion can occur across cell membranes, osmosis requires the membrane.
|In diffusion, pressure does not affect movement, in osmosis it does.
