Imbibition is the process of absorption of water by solid or colloidal substances. Swelling of seeds when immersed in water is an example of imbibition. Imbibition is the temporary increase in the volume of the cell. Imbibition is a passive transport of materials that does not require energy during the process.​ Different organic substances have different imbibing capacities. Proteins have very high imbibing capacity, higher than starch and starch has a higher imbibing capacity than cellulose.
