1. Flower Structure
LI : To recall the structure and function of the Flower

2. What did we learn last lesson?

3. Flowers

4. Flower structure

6. Stamen Structure
Stamen Anther Filament Pollen grain Male sex cell

7. Female parts of a flower

8. Petals
Bright colours for attracting insects

9. Sepals
Protects the unopened flower

10. Nectary
Makes sugary nectar….
..to attract insects

11. Male parts of the flower
Stamen – male part of the flower. Produces pollen grains
Pollen – contains the male sex cells

12. Female parts of the flower
Ovary – female part of the flower containing the ovules
Ovule – contains the female sex cell
Stigma – where the pollen grain attaches

13. Sex cells
Humans
Sperm egg
Plants
Pollen grains egg cell

14. Flower structure

15. Flower dissection
Stick parts of flower onto paper and label different parts:
Petal
Stigma
Stamen
Ovary
Ovule
Pollen
Egg cell
Nectary

16. What have learned today?
Success Criteria:
I can describe the functions of the parts of flowers, ie sepal, petal, stamen, stigma, ovary, nectary.
I can successfully carry out a flower dissection to identify these parts .
