Question

Describe the three types of pollination that can occur in a chasmogamous bisexual flower.

Hint:

In oogenesis, meiosis is incomplete until fertilization. This ensures that the female gamete (ovum) is haploid, ready to merge with the male gamete during fertilization. In pollination, the main aim is to transfer pollen efficiently between flowers to ensure genetic diversity.

Answer 1

Pollination in Chasmogamous Bisexual Flowers:
Three types of pollination:
1. Self-pollination: Pollen from the same flower or plant fertilizes the ovule. It can be autogamy (within the same flower) or geitonogamy (between different flowers of the same plant).
2. Cross-pollination: Pollen from one plant fertilizes the ovule of a different plant. This increases genetic diversity.
3. Insect pollination: Pollen is transferred between flowers by insects, such as bees, enhancing cross-pollination.
