Vedclass · Answer

(C) Imbibition is a special type of diffusion where water is absorbed by solids (colloids),causing them to increase in volume.Seeds contain hydrophilic colloids like proteins and starch,which have a very low (highly negative) water potential.When a dry seed is placed in water,a steep water potential gradient is established between the water (high water potential) and the seed (very low water potential).Due to this gradient,water moves into the seed,causing it to swell.
