Study Notes
Pollination Overview
- Pollination is the transfer of pollen from a plant's anther (male part) to its stigma (female part), fertilizing the plant and creating seedlings.
Cross-Pollination
- Cross-pollination is the most common type.
- Plants attract animals (birds, insects) with bright colors, smells, and shapes.
- Animals carry pollen from one plant's anther to another's stigma.
- Example: A butterfly lands on a flower, pollen sticks to its legs, and is transferred to another flower.
Seedling Formation
- Pollen travels to the egg after landing on the stigma, fertilizing the plant.
- A seed forms which is dispersed by wind, water, animals, or humans.
- Animals can eat seeds and spread them through their waste.
Other Pollination Methods
- Self-pollination: Plants fertilize themselves without outside help (e.g., tomatoes).
- Wind-pollination: Plants with dry pollen and feathery flowers (e.g., trees and grasses) use wind to spread pollen.
- Water-pollination: Plants in ponds and lakes release pollen into the water to travel to other plants.
Importance of Pollination
- Pollination is crucial for plant reproduction.
- Plants provide food, clothing, shelter, oxygen, and habitat for animals.
- Without pollination, life on Earth as we know it would not exist.
