1. Flower Parts (K. Plantae)
Unit 2 - Biodiversity

2. Angiosperms Have unique reproductive organs called flowers
Flowers contain ovaries, which surround and protect the seeds.
The seed is enclosed
Ovary develops into a fruit, which protects the seed and helps on dispersal.
Contains both male and female parts

3. Flower Parts The female part is called the pistil or the carpel.
The male part is called the stamen.

4. Stamen The male reproductive structure of a flowering plant.
Consists of two parts
anther
Contains pollen
Filament

5. Parts of the Stamen Anther
the structure located on top of the stamen and carries the pollen

6. Parts of the Stamen Pollen
Pollen is the male sex cell that donates half of the DNA to make a seed.
It is a powdery substance, usually orange or yellow in color, that gets carried by pollinators.

7. Parts of the Stamen Filament
a thread-like part that holds up the anther

8. Pistil/Carpel
the female reproductive structure of a flowering plant

9. Parts of the Pistil/Carpel
The innermost flower part
Produces female gametes (ovule)
Consists of three parts
Stigma
Style
Ovary

10. Parts of the Pistil/Carpel
Stigma
the sticky surface on the top of the pistil; it traps and holds the pollen.

11. Parts of the Pistil/Carpel
Style
the tube-like structure that holds up the stigma

12. Parts of the Pistil/Carpel
Ovary
the plant part at the bottom of the flower that has ovules inside
this turns into the fruit and seeds we eat.

13. Parts of the Pistil/Carpel
Ovules
the female sex cells inside the ovary that donate half the DNA to become the seed.
(They become the seeds when pollinated or fertilized by the pollen.)

14. Other Flower Parts Petal
the colorful flower parts that surround the reproductive structures.
Function is to attract pollinators

15. Other Flower Parts Sepal
the green petal-like parts at the base of the flower; they help protect the bud when it develops

16. Perfect Flowers Perfect
flowers that have both male and female parts (ex. Roses, lilies, and pea plants)

17. Imperfect Flowers Imperfect:
flowers with male or female parts (ex- cucumbers, pumpkins, and melons

18. Pollinators
A pollinator is something that moves pollen from the male parts to the female parts.
