  1. The Parts of the Flower Section 8-5 Focus On: • Parts of a flower (male & female) • Pollination, Fertilization, Germination. • Comparing Angiosperms to Gymnosperms

  2. Section 8-4: Gymnosperms & Angiosperms V. Gymnosperms: The Naked Seed A. There are FOUR phyla of Gymnosperms: Phyla: Example: 1) _____________ _________________ 2) _____________ _________________ 3) _____________ _________________ 4) _____________ _________________ Conifers Redwood Cycads Palm Trees Ginkgoes Maiden Hairs Gnetophytes Tropical Vines

  3. Section 9-3: Gymnosperms & Angiosperms • The largest group of gymnosperms are the • ________________. • The word conifer actually means: ______________________. • VI. Angiosperms: The Coated Seed • A. Angiosperms: _____________________ • _______________________________ • Angiosperms can be found all over the world, even where it is cold. Conifers Cone-bearer Make up the largest group of plants–they vary greatly.

  4. Section 9-3: Gymnosperms & Angiosperms • Angiosperms are the flower producers. • Flowers are: ________________________ • ___________________________________ • _________________________________ • C.The general structures and their functions in flowers: • 1) sepals: __________________________ • _________________________________ • 2) petals: _________________________ • _________________________________ The structures that have the reproductive organs in angio-sperms. Support and protect the base of the flower. Used to attract organisms for pollination. Also can protect.

  5. Petals Sepals Parts of a Flower

  6. Section 8-5: The Parts of a Flower THE MALE FLOWER PARTS: 1) stamen: _________________________ ________________________________ 2) anther: _________________________ ________________________________ 3) filament: ________________________ ________________________________ 4) pollen: __________________________ The entire male part of the flower. Knob-like structure where pollen is stored and made. Supports the anther. Male sex cell of plants.

  7. Section 8-5: The Parts of a Flower THE MALE FLOWER PART Pollen Anther Stamen Filament

  8. Section 8-5: The Parts of a Flower THE FEMALE FLOWER PARTS: 1) pistil: ___________________________ ________________________________ 2) stigma: _________________________ ________________________________ 3) style: ___________________________ ________________________________ 4) ovule: __________________________ 5) ovary:__________________________ The entire female part of the flower. Sticky opening on the pistil top where the pollen enters. Tube on the pistil where the Pollen travels to get to the egg. Female sex cell of plants. Contains the ovule.

  9. Section 8-5: The Parts of a Flower THE FEMALE FLOWER PART Stigma Pistil Style Ovary Ovule/Egg

  10. Section 8-5: The Parts of a Flower A grain of pollen lands on the stigma of the pistil. • A flowering plant is pollinated when • ___________________________________ • ___________________________________ • Label the flower diagrams in your notes. • E. Fruits of Flowering Plants. • 1) The fruit is: ______________________ • __________________________________ • 2) The seed of the flower is located ___________________________________ • __________________________________ The ripened ovary that Holds, protects, & feeds the seed. In the center of the ovary (fruit) This seed is the fertilized egg.

  11. Reviewing this Section: Pollination $ What are the two parts to a flower? $ What is the function of the sepal? $ How do flowering plants reproduce? $ Give an example of an angiosperm. $ What is the process that is happening here.

  12. Thank you for a GREAT year!
