Question
Define and or explain the term:
imbibition
Solution
Imbibition is swelling up of hydrophilic colloids due to the absorption of water.
OR
- The absorption of water by hydrophilic compounds is called imbibing.
- A substance that absorbs water or liquid is called imbibant, and water or liquid that is imbibed is called imbibate.
- The root hair cell wall is made up of pectic compounds and cellulose, which are hydrophilic colloids.
- During imbibition, water molecules get tightly adsorbed without the formation of a solution.
- Imbibition continues until the equilibrium is reached. In other words, water moves along the concentration gradient.
- Imbibition is significant in soaking seeds, swelling up of dried raisins, kneading of flour, etc.
