Answer :

Final answer:

Pollination is crucial for seed production in angiosperms, involving the transfer of pollen from the male anther to the female stigma. The most common methods of pollination include self-pollination and cross-pollination, each with distinct definitions and outcomes. Understanding these processes enhances our knowledge of plant reproduction and biodiversity.


Explanation:

Pollination and Its Importance

Pollination is a critical process in the reproduction of flowering plants (angiosperms). It involves the transfer of pollen from the anther (the male part) to the stigma (the female part) of a flower. This process is essential for the formation of seeds, as the pollen must fertilize the ovule for a seed to develop.

1. Why is pollination important?

  • C. To produce seeds - This is the correct answer as pollination is directly responsible for seed production after the pollen fertilizes the ovule.

2. Most Common Method of Pollination

  • A. Self-pollination - This method is when pollen from the same flower lands on its own stigma, making it common and straightforward.

3. Definition of Self-Pollination

  • A. Self-pollination - This occurs when the pollen from one flower fertilizes the ovule of another on the same plant.

4. Definition of Cross-Pollination

  • D. The transfer of pollen from the anther to the stigma of another flower of another plant but of the same kind. - This definition accurately describes cross-pollination and its significance in promoting genetic diversity among plants.

Both self-pollination and cross-pollination have their advantages, with cross-pollination typically leading to greater genetic diversity and adaptability in plants.
