1 Parts of a Flower PA Standards

2 4- Parts of a Flower Stamens Stamens 1- Male reproductive organs

3 Stamens 2) Have two parts Filament- stalk Anther- where pollen is made

4 Pollen released into the air
Pollen grain forming on anther

5 Stamen Flower Parts

6 Flower Parts Anthers

7 Flower Parts Filament

8 4- Parts of a Flower b) Pistils 1- Female reproductive organs Pistil

9 2) Pistils have three parts
Ovary – produces ovules (female gametes) Style – short stalk Stigma – sticky extension of stalk that catches pollen.

10 Pistil parts

11 Pistil ovary Ovules growing in the ovary

12 Pollen sticking to the pistil’s stigma. Pistil Stigmas

13 Pistil Flower Parts

14 Flower Parts Stigma Style Ovary

15 Sepals & Petals C) Sepals- Leaflike parts that protect the flower.
d) Petals – Attract pollinators.

16 Flower Parts Petal Sepal

17 How does pollen get from the stamen to the pistil?
Insect Pollinators Wind

18 Humans can also selectively pollinate flowers:
Taking pollen from one plant with a certain trait and placing it on a plant with a different trait. For example, taking pollen from a short plant and placing it on a plant that is tall. Cross pollination

19 Seed & Fruit Production
a) After pollen lands on stigma a tube grows down the style to an ovule.

20 Seed & Fruit Production
b) The fertilized zygote develops into a seed.

21 Seed & Fruit Production
c) The ovary that surrounds the ovules develops into a fruit.

22 Seed & Fruit Production
c) The ovary that surrounds the ovules develops into a fruit (if the fruit dries out it becomes a shell). Produces nuts, grains Acorns, etc.

23 Tomato flower develops into fruit.
