  2. Sepals

  3. Structure of Flowers • Sepals and Petals • Sepals • usually green and found at the base of a flower • enclose the bud before it opens • protectthe flower while it is developing

  4. Petals

  5. Structure of Flowers 2. Petals • Often brightlycolored • Found inside the sepals • Attract insects and other pollinators to the flower

  6. 1. Sepals2. Petals • These are sterile leaves because they do not have reproductive cells

  7. Anther Stamen Filament

  8. Structure of Flowers 3. Stamen – • male reproductive parts. • Each plant has several stamens made up of two parts- • Anther-Produces pollen • Filament- Holds up the anther so pollen is accessible

  9. Stigma Carpel Style Ovary Ovule

  10. Structure of Flowers 4. Carpel (pistil) - • Female reproductive parts. • Each plant will have only one carpel a. Stigma • Sticky portion at the top of the style for pollen to attach b. Style • A narrow tube that leads to the ovary c. Ovary • Contains one or more egg or ovule – the female gamete
