  1. FLOWERS By: Chelsye DeBoor

  2. Important Parts of a Flower • 4 main parts • Sepal • Petal • Pistil (or carpel) • Stamen

  3. Sepals • Protect flower while developing from bud • Look like green little leaves • Collectively called CALYX

  4. Petals • Member of COROLLA • All the petals make the corolla • Brightly colored part of a flower • Used to attract pollinators

  5. Female Parts: PISTIL • Sits on the receptacle • Made of 4 parts: • Stigma • Style • Ovary • Ovule

  6. 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

  7. Male Parts: STAMEN • 3 parts • Anthers • Connective • Filament

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

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

  10. Types of Flowers • Imperfect • Perfect • Complete • Incomplete

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

  12. Imperfect flower • Has ONLY one type of reproductive organs • STAMEN OR PISTILS • Requires 2 flowers (1 male, 1 female) to reproduce • Examples: • Corn • Cucurbit family • Melons, gourds, cucurbits (cucumbers)

  13. Male vs. Female Corn

  14. Male vs. Female Cucurbit

  15. Complete Flower • Has all 4 parts • Sepals, petals, pistil, stamen • All complete flowers are perfect, but not all perfect flowers are complete. Why???

  16. Complete Flower • Examples: • Roses, zinnia

  17. Incomplete Flower • Lacks one or more of the 4 parts • Examples: • Cucurbitaceae family • Melons, gourds, cucurbits (cucumbers) • Calla lily

  18. Monoecious • 2 options: • Plant has perfect flowers (both sexes) • Plant has separate male and female flowers located on the same plant • Examples: • Easter Lily, pea, dandelion, rose

  19. Dioecious • Has imperfect flowers on separate plants • One plant is male, one plant is female • Need 2 plants to reproduce • Examples: • Cucurbitaceae family

  20. Monocot • Embryo growth with single cotyledon • Flower parts in multiples of 3 • Major leaf veins run parallel • Stem vascular bundles scattered • Roots are adventitious • Secondary growth absent • Pollen with single pore

  21. Dicot • Embryo growth with 2 cotyledons • Pollen with 3 pores • Flower parts with multiples of 4 or 5 • Stem vascular bundles in a ring • Roots develop from radicle • Secondary growth present • Major leaf veins are netted
