  4️⃣ Pistil
• What is the primary function of the anther in the stamen?

  Produce pollen
• Petals in a flower are often colourful to attract pollinators

• Which part of the pistil contains the ovule for seed development?

  Ovary
• What are the two main parts of the stamen?

  Anther and filament
• What are the three main parts of the pistil?

  Ovary, style, and stigma
• Sepals are green, leaf-like structures that protect the bud

  2️⃣ Fertilization

  3️⃣ Seed development
• What is the role of sepals in pollination?

• Petals are often colorful and scented to attract pollinators
• Which floral part produces pollen?

  Stamen
