Question

Why do some plants have both chasmogamous and cleistogemous plants flowers?

✓

Answer

When flowers open, their sex organs are exposed for further process of fertilization then it is chasmogamous condition.
Pollinating agents can easily transfer pollen grains in such flowers for self as well as cross pollination.
When flowers are closed, they are self pollinated in bud conditions then this condition is cleistogamy.
When some plants have both of these types of flowers it ensures pollination and fertilization leading to seed setting. When seeds are formed then perpetuation of species is achieved as new plants will germinate from it.
