Germination is the initiation of seed growth. It is the process in which plumule and radical are grown from the seed which grow into a new plant. Epigeal and hypogeal germination are the two types of germination. The basic difference between them is that in hypogeal germination the cotyledons also called as seed leaves remain below the surface of the soil and the shoot grows outward whereas in epigeal germination the cotyledons are brougt outward above the ground along with the shoot. The example of hypogeal germination is pea plant and that of epigeal germination is Ash tree.
