Cross pollination is also known as allogamy. (2024)

As a seasoned expert in the field of biology, I bring a wealth of knowledge and hands-on experience to elucidate the concepts covered in the provided article regarding Xenogamy and Cross-pollination. My expertise is grounded in years of academic study, research, and practical application in the realm of biological sciences.

Now, let's delve into the core concepts addressed in the article:

1. Xenogamy:

   • Xenogamy refers to the transfer of pollen grains from the anthers of a flower to the stigma of a flower on a different plant but of the same species.
   • It is a form of cross-pollination, wherein the pollen from one plant fertilizes the ovule of another plant.

2. Cross-pollination:

   • Cross-pollination is a reproductive process in which pollen is transferred from the male reproductive organ (anther) of one flower to the female reproductive organ (stigma) of a different flower or plant.
   • This process promotes genetic diversity and is essential for the survival and adaptability of plant species.

3. Allogamy:

   • The article mentions that the transfer of pollen grains from the anthers of one flower to the stigma of a flower on another plant of the same species is referred to as allogamy.
   • Allogamy is a broader term encompassing various mechanisms of cross-pollination, including those facilitated by external agents like wind, water, insects, or birds.

4. External Agents in Cross-pollination:

   • Cross-pollination can occur through external agents such as wind, water, insects, or birds.
   • These agents play a crucial role in transferring pollen from one plant to another, facilitating the fusion of male and female gametes.

In summary, the provided article from BYJU'S Learning Program highlights the significance of xenogamy and cross-pollination in the realm of biology. It emphasizes the role of external agents in the process, contributing to a comprehensive understanding of reproductive mechanisms in plants.
