Imbibition
Imbibition
Imbibition (/ɪmˌbɪbɪˈʃən/) is a special type of diffusion when water is absorbed by solids-colloids causing an enormous increase in volume. The term is derived from the Latin word imbibere, meaning "to drink in".
Etymology
The term "imbibition" comes from the Latin imbibere, which means "to drink in". It was first used in the context of biology in the 19th century.
Process
Imbibition is the process by which water is absorbed by solids, colloids, and in particular, by plant tissues. This process is responsible for the initial stage of water absorption in seeds, dry wood, and other similar substances. The pressure that is exerted by the absorbed water in the process of imbibition is called imbibition pressure.
