Explain how Self pollination in favoured in cleistogamous flowers
Answers
Answer:
Self pollination is type of pollination in which pollen from the anther of a flower lands on the stigma of the same flower or another flower of same plant.
Cleistogamous flowers are the types of flower which do not open at all.
In addition, the anther and stigma lie in close proximity.
It ensures that pollen from the anther arrives on the stigma of the same flower.
Hence, they are invariably autogamous in nature. Also, they can pollinate in absence of pollinators.
For example, this phenomenon is mostly observed in peas, peanuts etc.
The cleistogamous flower self-pollination shows the mixed mating method. This is shown in the maximum of 42% of the plant that is flowering.
This type of system is the one where a single flower produces with the self-pollination.
This is referred to as the dimorphic cleistogamy where the plant opens up the produces the out-crossed.
