Ans. On the basis of the elongation of hypocotyl and epicotyls, there are two types of germination. In epigeal germination, the hypocotyl elongates and forms a hook, pulling the cotyledons above ground, e.g., beans, cotton, papaya germinate in this way. In hypogeal generation, the epicotyl elongates and forms the hook. In this type of germination, the cotyledons stay underground. Pea, maize and coconut germinate this way. Figure 14.16
