Significance Imbibitions in Plant Life

Imbibitions: The process how a colloidal substance (completely or partially dried) absorbs water is said to be imbibitions.


Imbibition is the phenomenon of adsorption of water by the solid particles of a substance without forming a solution. The substances that absorb water are known as hydrophilic substances. The colloidal substances are hydrophilic in nature Cellulose, starch etc. present in the plant boils are colloidal substances. They swell up by absorbing watt and contract by losing water. The process of absorption of these kinds of colloidal substances is known as imbibitions. Imbibition is a special type of diffusion when water is absorbed by solids-colloids causing an enormous increase in volume.

Example: The amount of water that a dry seed absorbs before germination is almost absorbed by imbibitions method.

Importance of imbibitions

  • The first step of water absorption by root hairs from soil is performed by imbibitions.
  • Dry seeds become fit for germination by absorbing water through imbibitions method. The germination of seeds is dependent on imbibitions method.
  • Imbibitions are dominant in the initial stage of water absorption by roots.
  • The water moves into ovules which are ripening into seeds by imbibitions.
