Explain how self pollination is favoured in cleistogamous flower
Asked by collinkalayilroy | 14th Oct, 2018, 05:42: PM
In cleistogamy, the flowers are intersexual. They remain closed causing self-pollination. In these flowers, anthers and stigma lie close. When the dehiscion occurs in the flower buds by anthers, pollen grains come in contact with stigma to effect pollination which blocks the path of cross-pollens. For example- Balsam

- Assertion :- In sun-flower family petals are modified in to pappus. Reason :- Pappus helps in dispersal of flower.
