1. Flowers & Pollination

2. What is a Flower?
A flower is the part of the plant that makes the seeds.

4. Male Parts of a Flower

5. Male Parts of the Flower
Stamen:
Male part of the flower
Made up of the filament and anther
Contains the pollen which is the male reproductive cell
Anther
produces and contains pollen.
It is usually on top of a long stalk that looks like a fine hair.
Filament
Holds the anther
This is the fine hair-like stalk that the anther sits on top of.

7. Female Parts of a Flower

8. Female Parts of the Flower
Pistil
Female part of the flower
Made up of the stigma, style, and ovary.
Stigma
Receives the pollen grains and on which they germinate.
It is the sticky bulb that you see in the center of the flowers
Style
This is the long tube connecting the stigma to the ovary.
Ovary
Female reproductive organ.
Usually at the bottom of the flower,
Has the seeds inside and turns into the fruit that we eat.
Contains ovules or eggs.

Stigma
Style

10. Other Important Parts of a Flower
Petal The colorful, often bright part of the flower. They attract pollinators and are usually the reason why we buy and enjoy flowers.
Sepal The parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens.

11. What is Pollination
Pollination: the transfer of pollen from the anther of one flower to the stigma of another flower.
Fertilization: occurs when the sperm in the pollen unites with an egg.

12. Pollinators
Since flowers can't move, they need to be able to attract pollinators or be built so that wind is able to pollinate them.
Pollinators!
Wind
Butterflies
Bees
Bats
Birds
Insects
Flowers attract pollinators with sweet nectar, bright colors, and shapes and structures.
Some flowers open at special times to attract pollinators such as night blooming plants that are pollinated by bats.

13. How Pollination Happens
The bee goes to a flower in search of nectar to eat.
While the bee is there, the bee rubs against the anther and some pollen gets on his bee fur.
The bees goes to another flower for some more nectar.
While on that flower, some of the pollen sticks to the sticky stigma.
The pollen travels down the style into the ovary.
The sperm in the pollen fertilizes the eggs in the ovary to form seeds.

14. Flower Parts You Need to Know
stamen – male part (anther & filament)
anther – makes pollen
filament – hair-like structure; hold up the anther
pistil – female part (stigma, style, ovary)
stigma – sticky; catches pollen
style – tube that pollen travels down
ovary – contains eggs
pollen – yellow powder; fertilizes eggs
seeds – makes new flowers
pollinators – wind, insects, bees, bats, birds

15. Angiosperm
Angiosperm – is plant that has flowers and produces seeds enclosed within a pistil. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.
Angiosperms are the most diverse group of land plants, with 416 families.
