Question : The process of imbibition involves
Option 1: Diffusion
Option 2: Capillary action
Option 3: Absorption
Option 4: Both 1 and 2
Correct Answer: Absorption
Solution : The correct option is Absorption.
Absorption of water by solid things, particularly porous materials such as plant tissues or powdered solids, is the process of imbibition. Imbibition happens when water molecules are drawn into the substance by capillary action, causing swelling and expansion. This process is critical in various biological and physical situations, including seed germination, swelling of dry materials and water transport in porous media.
