**Imbibition** is the process of:
AMovement of solvent through a semipermeable membrane
BAdsorption / absorption of water (or any liquid) by hydrophilic colloids, causing them to swell
CActive uptake by ion pumps
DLoss of water as vapour from leaves
Answer & Solution
Correct answer: B. Adsorption / absorption of water (or any liquid) by hydrophilic colloids, causing them to swell
Imbibition: hydrophilic colloids (cellulose, pectin, proteins) adsorb water and swell. Examples: soaking of seeds before germination, swelling of dry raisins, kneading of dough. The imbibing substance is 'imbibant'.
