In process of pollinating flower, there is a transfer of "pollen."
Pollen: contanins the male nuclei + source of protein.
Transferred by: Insects.
Cross pollination: insects take pollen from one flower to another.
They get attracted by signals: brightly colored petals, petal shape, + food reward – pollen &/or nectar, fragrance
Carpel: Female organs of flower:
- Stigma: collects the pollen from the pollinating insect , & stimulates pollen germination.
- Style: positions the stigma for effective pollen collection.
- Ovary: site of fertilisation, protects the developing seeds, aids in seed dispersal.
- Anther: pollen formation & release.
- Filament: positions the anther for effective pickup of pollen by the pollinating insect.
