Imbibition is a special type of diffusion when water is absorbed by solids-colloids causing an enormous increase in volume. ... Imbibition is also diffusion since water surface potential movement is along a concentration gradient; the seeds and other such materials have almost no water hence they absorb water easily. When a seed absorbs water, it is called imbibition. Water enters the seed either through a tiny opening in the seed called the micropyle or through the seed coat. ... The scarred seed coat is permeable, allowing water to pass through and germination to begin. Other seeds require cold temperatures before they can germinate.
