Osmosis | Diffusion |
Osmosis occurs in liquid medium. | Diffusion occurs in all mediums. |
Osmosis needs a semipermeable membrane for the process to happen. | Diffusion does not require a semipermeable membrane. |
Osmosis occurs only between similar types of solutions. | Diffusion occurs between both similar and dissimilar types of solutions. |
Osmosis requires water for the movement of particles. | Diffusion does not require water for the movement of particles. |
Only the solvent molecules can diffuse in osmosis. | Both the solute and solvent molecules can diffuse in diffusion process. |
The flow of particles in osmosis occurs only in one direction. | The flow of particles in diffusion occurs in all directions. |
Osmosis doesn’t help in the uptake of minerals and nutrients. | Diffusion helps in the uptake of minerals and nutrients. |
