Which of the following options is correct?a)Transfer of pollen grains ...
Autogamy (Gk. autos-self, gamos-marriage) is a type of self-pollination in which an intersexual or perfect flower is pollinated by its own pollen.
Geitonogamy is a type of pollination in which pollen grains of one flower are transferred to the stigma of another flower belonging to either the same plant or a genetically similar plant. In geitonogamy, the flowers often show modifications similar to ones found in xenogamy or cross-pollination.
Xenogamy or cross-pollination is the transfer of pollen grains from the anther of one flower to the stigma of a genetically different flower.

Which of the following options is correct?a)Transfer of pollen grains ...
Introduction:
The question pertains to the different types of pollination, which is the transfer of pollen grains from the anther to the stigma of a flower. There are three main types of pollination: autogamy, geitonogamy, and xenogamy.
Explanation:
1. Autogamy:
Autogamy refers to the transfer of pollen grains from the anther to the stigma of the same flower. This can occur within a single flower or between different flowers on the same plant. It is a type of self-pollination, where the plant can reproduce without the need for external pollen transfer.
2. Geitonogamy:
Geitonogamy involves the transfer of pollen grains from the anther of one flower to the stigma of another flower on the same plant. This type of pollination also falls under self-pollination, as the pollen is transferred between flowers of the same individual plant.
3. Xenogamy:
Xenogamy is the transfer of pollen grains from the anther to the stigma of a genetically different plant. This is a form of cross-pollination, where pollen is transferred between flowers of different plants. It promotes genetic diversity and is essential for the survival and evolution of plant populations.
Conclusion:
The correct option is 'D) All of these' because it encompasses all three types of pollination discussed above. Autogamy and geitonogamy are forms of self-pollination, while xenogamy is a type of cross-pollination. All three types of pollination play important roles in plant reproduction and contribute to the overall diversity and success of plant populations.
