Stamen - male part - makes the pollen (anther and filament)
![Page 4: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/4.jpg)
Pistil - female part (stigma, style and ovary)
![Page 5: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/5.jpg)
Sepals - holds petals closed until the flower is ready to bloom

Petals - Part that protects the stamen and pistil

Pollination - when the pollen from the male stamen reaches the female pistil
![Page 8: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/8.jpg)
Self-pollinating: plants can pollinate themselvesAsexual Reproduction - exact copy of parent
![Page 9: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/9.jpg)
Cross-pollinating: plants get pollinated from another plant Sexual Reproduction - combination of two parents
![Page 10: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/10.jpg)
Pollination…1) Animals2) Wind
3) Water

Pollination - 80% of pollination occurs with help from animals
![Page 12: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/12.jpg)
Visual Cues - showy petals, nectar guides (darker color in center - bees can see, humans can’t), flower shape and size, color

Scent - usually plants that are not very colorful have a very strong scent (odor) to attract animals
![Page 15: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/15.jpg)
Food - pollinators get food - nectar - from plants (nectar - is sugar water with other nutrients)
![Page 16: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/16.jpg)
Mimicry - some plants mimic animals/insects to attract pollinator - scents, looks (animals/insects think the plant is a mate)
![Page 17: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/17.jpg)
Entrapment - some plants trap pollinators - they may use a combination of the other strategies to draw the animal/insect in

ANIMAL POLLINATORS● ants ● bats ● bees ● beetles ● birds ● butterflies ● moths ● wasps ● black and white ruffed lemurs ● honey possum

Pollination - 80% of pollination occurs with help from animalsSO, 20% is without help from animals… most of this is done by
the wind (98% of the 20%).

● No bright colors, special odors, or nectar● Small● Most have no petals● Stamens and stigmas exposed to air currents● Large amount of pollen● Pollen smooth, light, easily airborne● Stigma feathery to catch pollen from wind● Usually single-seeded fruits, such as oak, grass, birch, poplar, hazel, dock, cat-tail, plantain, and papyrus

Water (2% of the 20% of pollination happens with
water)- pollen floats on the surface of water until it reaches plants - water
pollinated plants are aquatic plants

Seed Dispersal…1) WIND
2) WATER3) ANIMALS
![Page 23: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/23.jpg)
Every fertilized ovule becomes a seed. Dispersal is important, because the young plants must sprout away from the
parent plants. Wind, water and animals are agents of dispersal.
![Page 24: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/24.jpg)
Wind does not need an incentive to carry seeds.
The plant must form its seed in a shape that will let it fly.
(maple / dandelions)

When thistle dries out, the whole things rolls around in the wind, spreading seeds!
![Page 26: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/26.jpg)
Many aquatic plants rely on water. There are also many land plants that rely on water for dispersal of their seeds. Palm trees release coconuts
which can float for days at sea.
![Page 27: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/27.jpg)
Animals carry seeds in many ways. Some seeds stick to fur and feathers
and are carried wherever the animal
travels. They fall (or are scratched) off and
sprout where they land.
![Page 28: Plants! - Weebly](https://reader031.fdocuments.us/reader031/viewer/2022012916/61c723e9e7a19a7a42070365/html5/thumbnails/28.jpg)
Many animals store nuts for the winter. A nut is a hard, wood like seed. The plant makes them difficult to eat. Some of the buried seeds sprout in spring, far from the parent plant.

When a plant creates a fruit, it hides the fertilized ovules (which are now seeds) inside an enticing treat. Why is
this? What type of seed dispersal does this use?
