1. Angiosperms

2. Why a Flower?

3. A flower is made up of rings
The outermost ring is made of sepals
The next ring inside of the sepal are the petals
Inside the petals are a ring of stamen
And last, in the CENTER of the flower is the pistil

4. The Reproductive Structure of Flowering Plants:
Perianth
Petal: Corolla
Sepal:Calyx

5. Flower Anatomy Flowers contain the reproductive parts of angiosperms.
When a flower is still a bud, it is
enclosed by leaf-like structures
called sepals
These structures help
protect the flower. .

6. Flower Anatomy The petals attract pollinating insects with
their bright color and
attractive scent .
The coloration may extend into the ultraviolet, which is visible to the compound eyes of insects, but not to the eyes of birds.

7. Petals The patterns on the inside of the petals often act as
“landing strips” for insects.
It helps guide insects to
the male and female
reproductive structures
within the flower

8. Flower Anatomy  The petals also surround the reproductive organs.
The stamen has two parts.
filament
. anther

9. The stamen is made of two parts the Anther and the Filament.
The Parts of a Stamen
The stamen is made of two parts the Anther and the Filament.
Filament
Anther
The Filament is a stalk like structure that holds up the Anther.
The Anther produces the pollen cells.

10. Flower Anatomy In the center of the flower are
the pistils (also known as the carpel)

11. Flower Anatomy The pistils are the female organs of the flower.
The stigma is at the very top
of the pistil.
A sugary fluid makes the stigma
sticky, and keeps the
pollen from falling off or
blowing away.

12. Flower Anatomy The pistils of most flowers have three parts.
At the base of the flower is the hollow ovary, which contains
the egg cells (ovule)
A slender tube, called the style, connects the stigma to the ovary.
Fertilization takes place in the ovary.

13. ijhpFlower Anatomy
fertilization
carpel structure

14. Fruit and Seed Formation
A fruit develops from an ovary. A seed develops from an ovule.

15. Flower Structure Variation
A flower having sepals, petals, stamens, and pistils is complete; if a flower is lacking one or more of these whorls, it is said to be incomplete.
complete
incomplete
no stamens present = incomplete

16. Pollen Dispersal by Animals
Bees, Beetles, Bats, Birds, Butterflies, etc…

17. Dicot versus Monocot
