Topics in Pollination and Fertilization

1. Pollination: Meaning and Types

  • Pollination is the process of transference of pollen grains from the anther to the stigma.
  • Pollination must occur between plants of the same species for successful reproduction; pollen of other species fails to germinate.
  • There are two kinds of pollination: self-pollination and cross-pollination.

2. Devices That Favour Cross-Pollination

  • Nature has several devices that favour cross-pollination.
  • Unisexuality promotes cross-pollination because male and female flowers are separate.
  • In papaya, male and female trees are usually separate, though rare hermaphrodite trees also occur.

3. Agents of Cross-Pollination

  • The two commonest agents of cross-pollination are insects and wind.
  • Water, birds, and elephants can also act as pollinating agents in some plants.
  • Insect-pollinated flowers are large, brightly coloured, scented, nectar-producing, and have sticky or spiny pollen and a sticky stigma.

4. Fertilization and Double Fertilization

  • Fertilisation is the union or fusion of the nuclei of male and female gamete.
  • The pollen grain is the male gamete.
  • The ovule inside the ovary is the female gamete.
