Flowers and Reproduction

2. Parts of a Flower Petals
Petals are like signs that tell POLLINATORS to come to the flower
Petals tell insects and birds that there is yummy nectar to eat

3. Parts of a Flower Flowers have BOTH male and female parts
The male parts make up the STAMEN
The stamen are involved in making POLLEN

4. Parts of a Flower The female parts of the flower are called the PISTIL
The female parts CATCH the POLLEN and make seeds grow

5. STAMEN
PISTIL
ANTHER:
Releases pollen
STIGMA:
Collects Pollen
STYLE:
Pollen travels
down style
FILAMENT:
Holds up the
anther
OVARY:
Where seed is
made and held

6. Pollen and Plant Reproduction
Plants reproduce
They make seeds that grow into new plants
Pollen leaves the male parts of a flower
The pollen grains land on the female STIGMA of a different flower
This is called POLLINATION

7. How does the pollen get from one flower to another flower?
Pollen grains are taken from one flower to another by animals, birds and insects
Animals, birds and insects that carry pollen are called POLLINATORS

8. How does the pollen get from one flower to another flower?
Pollinators are tricked into carrying the pollen grains
The pollen grains stick to the pollinators
The pollinators will travel from flower to flower and carry the pollen

9. Pollinators!

10. Pollinators!

11. Pollinators!

12. Pollination
Once the pollen grain lands on a female stigma there are lots of changes
The pollen grains get bigger and grow a tube
The tube moves down the style and fertilizes the egg in the ovary
This is called FERTILIZATION

15. Making seeds The fertilized egg turns into a seed
The chamber that holds the seed turns into a fruit
