  1. Learning Target: Anatomy of Flowers I Can… Identify the common anatomical structures of flowers and classify flower types based on structures present • I Will… • Label the structures of an ideal flower diagram • Examine the structures of a real ideal flower • Define the function of the floral structures • Classify flowers into categories based on structural components KEY CONCEPT: Flowers contain reproductive structures/organs protected by specialized leaves

  2. Receptacle – Tip of stem that contains developing floral parts Sepals – Outer leaves of receptacle, protect inner parts of developing flower Sepals Petals Stem Receptacle Stem – Support of flower and pollinator Petals – Brightly colored parts of flower designed to attract pollinators

  3. Stamen – Male reproductive structures Anther – Structure that produces pollen grains containing sperm Stamen Anther Filament Filament – Stalk-like structure that supports anther

  4. Pistil / Carpal – Female reproductive structures Stigma – Top of pistil, generally sticky to hold pollen grains Pistil / Carpal Stigma Style Ovary Ovule Style – Stalk-like mid section of pistil, connects stigma to ovary Ovary – Contains structures that form ovule (eggs)

  5. Flower Categories – Based on floral structures present Complete – Flowers made up of sepals, petals, stamen and pistil(s) [Contains all four regular parts] Incomplete – Flowers lack one or more of the four regular parts of a complete flower • Perfect – Flowers have both stamen and pistil(s), but not necessarily sepals or petals

  6. Flower Categories – Based on floral structures present • Imperfect – Flowers lack either stamen or pistil(s), and may or may not have sepals or petals • Male flower • Female flower Male Female

  7. Learning Target: Anatomy of Flowers I Can… Identify the common anatomical structures of flowers and classify flower types based on structures present • I Will… • Label the structures of an ideal flower diagram • Examine the structures of a real ideal flower • Define the function of the floral structures • Classify flowers into categories based on structural components KEY CONCEPT: Flowers contain reproductive structures/organs protected by specialized leaves

  8. Learning Check √: Anatomy of Flowers What are the male reproductive structures of a flower? What are the female reproductive structures of a flower? What is the difference between an incomplete but perfect flower and an incomplete imperfect flower?
