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:

The pollination that occurs in opened flowers is called chasmogamy. ... So, we can say that chasmogamous flowers exhibit both autogamy (self-pollination)and allogamy (cross-pollination). While, in Cleistogamous flower the anthers and stigma lie close to each other with in the closed flowers.
