Study Notes
Pollination
-
Nectar is a sweet liquid produced by flowers to attract pollinators, primarily insects.
-
Patterns and marks on flower petals serve as visual cues for pollinators, guiding them towards the nectar.
-
When an insect feeds on nectar, it rubs against the anthers, which transfer pollen onto the insect.
-
Attracted by bright colors, the insect moves to another flower.
-
The pollen from the previous flower is transferred to the stigma of the new flower, facilitating pollination.
Self-Pollination
- Involves pollen transfer from anther to stigma within the same flower.
- A simpler form of pollination compared to cross-pollination, which involves different flowers.
