Question

Why do some plants have both chasmogamous and cleistogamous flowers?

Class 12th​

Answer 1

Answer:

To promote cross-pollination, chasmogamous flowers often have strikingly colored petals and nectar guides/nectaries to attract and reward pollinators. ... The closed morphology of cleistogamous flowers hinders them from exposing their reproductive organs and forces self-pollination.

Answer 2

Answer:

(1) When flowers open, their sex organs are exposed tor further process of fertilization then it is chasmogamous condition.

(2) Pollinating agents can easily transfer pollen grains in such flowers for self as well as cross pollination.

(3) When lowers are closed, they are self pollinated in bud conditions then this condition is cleistogamy.

(4) 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.
