Difference Between Diffusion and Osmosis
The difference Between Diffusion and Osmosis is as follows:
|
Features |
Diffusion |
Osmosis |
|---|---|---|
| Definition | Movement of particles from high to low concentration due to random motion and kinetic energy | Movement of solvent (usually water) across a semipermeable membrane from low solute concentration to high solute concentration |
| Type of Movement | Particles of various substances move | Mainly involve water molecules |
| Medium | Can occur in gases, liquids, and solids | Typically occurs in liquids (like water) |
| Membrane Presence | May or may not involve a membrane | Involves a semi-permeable membrane |
| Solute Presence | Can involve the movement of any type of particle | Involves the movement of solvent (usually water) |
| Direction | From areas of high concentration to low concentration | From areas of low solute concentration to high solute concentration |
| Biological Significance | Facilitates various cellular processes, like nutrient transport | Vital for maintaining cell turgidity, balancing fluid levels |

Diffusion
Diffusion in biology is the movement of particles like ions and molecules from a region of higher concentration to a region of lower concentration. Diffusion is a type of passive transport and is important for the proper functioning of the cell because it maintains the gradient across the cell membrane. Diffusion finds application in various fields. In biology, it governs the movement of the particles across the cell membrane, in industries or chemistry, it influences reactions, heat transfer, and materials manufacturing.
