Diffusion and osmosis is which state the movement of solvent and solute according to the concentration.
Following are the difference between osmosis and diffusion.
Osmosis
|
Diffusion
|
|
Definition
|
Osmosis is the movement of solvent from semipermeable membrane from a lower concentration to higher concentration.
|
Diffusion is the movement of solute from an area of higher concentration to lower concentration.
|
Movement
|
In osmosis, only movement of solvent happens
|
In diffusion movement of solvent and solute happened.
|
Phase
|
Osmosis is possible only in liquid phase
|
Diffusion is possible in liquid and gaseous phase.
|
Function
|
Osmosis helps the maintaining water level in cells. help in transport the nutrient
|
Diffusion is important in creating energy help in exchange the gases in animals.
|
Rate
|
Osmosis is a slow process
|
Diffusion is a fast process
|
Semi permeable membrane
|
It requires the semipermeable membrane
|
It does not require the Diffusion semi permeable membrane.
