Style
Ovary
Ovule

7. Female Parts Continued
Stigma
Where pollen grains attach to
Style
Long filament structure
Prevents pollen contamination
Ovary
Protects ovule; becomes fruit when fertilized
Ovule
Becomes seed when fertilized

8. Male Parts: STAMEN 3 parts Anthers Connective Filament
Image:

9. STAMEN continued Anthers Filament Produce pollen
Contains thousands of pollen grains
Pollen contains male sex cells
Filament
Holds the anthers
Fine and hair like

11. Other Flower Parts Receptacle Peduncle (pedicel) The part of the
flower that holds
everything
together
Peduncle (pedicel)

12. Types of Flowers
Imperfect
Perfect
Complete
Incomplete

13. Perfect Flower Has both Pistil (Female) and Stamen (Male) Examples:
Lilies, Roses, dandelions, wheat, apple, tomato
IMAGE:

14. Imperfect flower Has ONLY one type of reproductive organs
STAMEN OR PISTILS
Requires 2 flowers (1 male, 1 female) to reproduce

Stem vascular bundles scattered
Roots are adventitious
Secondary growth absent
Pollen with single pore

23. Dicot Embryo growth with 2 cotyledons Pollen with 3 pores
Flower parts with multiples of 4 or 5
Stem vascular bundles in a ring
