1. FLOWER ORGANS
Biology

2. PLANT ORGANS
Some flower organs are responsible for support or function, but others function in a reproductive role.

3. PLANT ORGANS In general, flowers have four organs: Sepals Petals
Stamens
Pistils – one or more.

4. PLANT ORGANS
SEPALS
Sepals protect the flower bud and can look like small leaves or even resemble the flower’s petals.

5. PLANT ORGANS
PETALS
Petals are usually colorful structures that can both attract pollinators and provide them with a landing platform.

6. PLANT ORGANS
Sepals and petals, if present, are attached to a flower stalk, called a peduncle.

7. PLANT ORGANS
Most flowers have several stamens – the male reproductive organs.

8. PLANT ORGANS Stamens are composed of two parts:
1) Filament-supports the anther
2) Anther-Forms the pollen grains.

9. PLANT ORGANS
The female reproductive part of the flower is the pistil, located in the center of the flower.

10. PLANT ORGANS The pistil usually has three parts:
Stigma – tip of the pistil. This is where pollination occurs.
Style – Part that connects the stigma to the ovary
Ovary – contains one or more ovules which is where the egg forms.

11. PLANT ORGANS STRUCTURAL DIFFERENCES
Flowers that have sepals, petals, stamens, and one or more pistils are called complete flowers.
If one is missing, it is an incomplete flower.

Pollination mechanisms

13. PLANT ORGANS Pollination mechanisms
Animal pollination – insects or other small animals (bats, birds) move from flower to flower searching for nectar.
Wind Pollination
Self Pollination
