5. Differentiate between the following:
(d) Imbibition and Diffusion
| Imbibition | Diffusion |
|
Imbibition is a special type of diffusion when water is absorbed by solid colloids causing them to increase in volume. For example: absorption of water by seeds and dry woods |
Diffusion refers to the movement of solute molecules along a concentration gradient |
| It takes place both in living and dead cells. | It takes place in solids, liquids and gases. |
| It is a reversible process. | It is not a reversible process. |
