what is pollination class 10
Pollination (for Class 10) is the process of transfer of pollen grains from the anther (male part of a flower) to the stigma (female part of a flower).
It is the first essential step that leads to fertilisation and seed formation in flowering plants.
Simple definition (Class 10 level)
- Pollination is the transfer of pollen from anther to stigma of the same or another flower of the same species.
- It prepares the flower for fertilisation, which later forms seeds and fruits.
Types of pollination (you should know)
- Selfâpollination : Pollen is transferred from the anther to the stigma of the same flower or another flower on the same plant.
- Crossâpollination : Pollen is transferred from the flower of one plant to the flower of another plant of the same species.
Agents of pollination
Pollination does not happen by itself; it needs agents.
- Abiotic agents : Wind, water.
- Biotic agents : Insects (bees, butterflies), birds, bats and other animals.
Why pollination is important (exam point of view)
- Leads to fertilisation: after pollination, the pollen grain forms a pollen tube, reaches the ovule, and male gamete fuses with egg.
- Helps in formation of seeds and fruits, which allow plants to reproduce and maintain their species.
- Essential for crop yield (fruits, vegetables, grains) that humans and animals depend on.

|---|---|---|
| Basic meaning | Pollen from anther to stigma of the same flower/plant. | [3][1][9]Pollen from flower of one plant to flower of another plant of same species. | [1][3][9][7]
| Genetic variation | Low variation in offspring. | [9][7]High variation; mixes traits of two parent plants. | [7][9]
| Need for agents | Often no external agent needed. | [3][1]Needs wind, water, insects, birds etc. | [1][4][9][7]
