[Biology Class Notes] on Imbibition Pdf for EXAM

Seed coat rupturing during germination, the ascent of sap, absorption of water by root hairs are all examples of imbibition. One example of imbibition in nature is the absorption of water by hydrophilic colloids. Protein has a great barrier potential, so proteinaceous pea seeds are more inflammatory than starchy wheat seeds. Water imbibition increases the volume of imbibant, leading to imbibitional pressure (IP). Imbibition causes swelling of seeds when they are placed in the ground, or when mature seeds are immersed in water at room temperature. Also, during the monsoon, the wooden door swells due to noise.
