What is Pollination? Types, Agents & Significance – Class 12 & NEET Notes
Pollination is a crucial step in the sexual reproduction of flowering plants. It is a high-weightage topic for NEET and Class 12 Biology.
What is Pollination?
Pollination is the transfer of pollen grains from the anther to the stigma of a flower.
Types of Pollination
- Self-Pollination (Autogamy) – Pollen from the same flower falls on its own stigma.
- Cross-Pollination (Allogamy) – Pollen is transferred from one flower to the stigma of another flower.
- Geitonogamy – Transfer of pollen between two flowers of the same plant.
Agents of Pollination
| Agent | Example |
|---|---|
| Wind (Anemophily) | Maize, Wheat |
| Insects (Entomophily) | Sunflower, Rose |
| Water (Hydrophily) | Vallisneria, Hydrilla |
| Animals (Zoophily) | Birds, Bats |
Significance of Pollination
- Essential for fertilization and seed formation
- Helps in genetic variation through cross-pollination
- Important for crop production and food security
