Imbibition: It is the process of water or any other liquid being absorbed by the solid particles of a substance without producing a solution. It is a form of diffusion that occurs when water is absorbed by solids-colloids, resulting in a volume increase.

Imbibition in Plants

• It means water exposure by hydrophilic-protoplasmic and cell wall elements.
• It causes swelling of the seed which leads to the rupture of the seed coat or testa.
• It forms the first step in seed germination.
• It aids in the flow of water into the maturing ovules, which become seeds.
• It is required in the early stages of root water absorption.

Factors Affecting Imbibition

• pressure
• texture of the imbibant
• pH of the medium
• affinity of the imbibant for the imbibate.
