Osmosis and diffusion are two processes that involve the movement of molecules from an area of high concentration to an area of low concentration. Both processes play a vital role in the transport of essential nutrients and other chemicals within living organisms. This article will explore the differences between osmosis and diffusion, including how they differ in terms of their application and effects on cells.
About Difference Between Osmosis And Diffusion
| Concept | Difference |
|---|---|
| Osmosis | Movement of water molecules from an area of higher concentration to lower concentration through a semi-permeable membrane. |
| Diffusion | Movement of particles from an area of high concentration to low concentration without the need for a membrane. |
| Pressure/Force | In osmosis, pressure is required, while in diffusion, no external force is needed. |
| Rate | The rate of osmosis is slower than that of diffusion. |
| Direction | In osmosis, movement is only one-way; whereas in diffusion, it can be two-way. |
| Membrane | Osmosis requires a semi-permeable membrane, while diffusion does not require any. |
