| Diffusion
|
Osmosis
|
| Occurs in all mediums – Solid, Liquid and Gas.
|
It is limited only to the liquid medium.
|
| Do not require a semipermeable membrane.
|
Requires a semipermeable membrane.
|
| Both the molecules of solute and solvent can diffuse.
|
Only the solvent molecules can diffuse.
|
| The flow of particles occurs in all the directions.
|
The flow of particles occurs only in one direction.
|
| This process can neither be stopped nor reversed.
|
The entire process can either be stopped or reversed by applying additional pressure on the solution side.
|
| Occurs between the similar and dissimilar types of solutions.
|
Occurs only between similar types of solutions.
|
| It does not depend on solute potential, pressure potential, or water potential.
|
Depends on solute potential.
|
| It helps in the uptake of minerals and nutrients.
|
Not associated with uptake of minerals and nutrients.
|
| Transpiration is controlled by the processes, such as osmotic potential and water potential.
|
Evaporation is not controlled by any such process.
|
| It depends on the presence of other particles.
|
Depends on the number of solute particles dissolved in the solvent.
