Question

What are the possible types of pollinations in chasmogamous flowers. Give reasons.

Answer 1

Chasmogamous flowers

Chasmogamous flowers are the type of flowers which are open and therefore expose the anther and stigmas to the outer environment.

Types of pollinations in chasmogamous flowers

Types of possible pollinations in chasmogamous flowers are autogamy, geitonogamy and xenogamy.
● Autogamy is a type of pollination that occurs when pollen grains are transferred from the anther to the stigma of the same flower in a plant.
● Geitonogamy is the type of pollination that occurs when the stigma of a flower is pollinated with the pollen grains from another flower of the same plant.
● Xenogamy is the type of pollination when the stigma of a flower is pollinated with the pollen grains from the flower of another plant.

Reasons

Since the reproductive parts of a chasmogamous flower are accessible, all three modes of pollination are possible.
