6. ANGIOSPERMAE
CIRI-CIRI
• Ada bunga yang sesungguhnya
• Ada daun-daun yang pipih, lebar, dengan susunan
yang beraneka ragam
• Bakal biji/biji tidak tampak,karena terbungkus suatu
badan yang berasal dari daun buah yaitu putik.
• Selisih antara penyerbukan dan pembuahan relatif
pendek
• Adanya pembuahan ganda

7. Simplified overview of angiosperm life cycle

8. Review of an idealized flower

9. Lily

10. Types of Flowers
• Complete – have all four organs (sepals, petals,
stamens, carpels)
• Incomplete – Lack one or more organs
• Bisexual – has carpels and stamens
• Unisexual – has carpels or stamens
• Monoeicous – stamens and carpels located on same
plant
• Dioecious – carpels and stamens located on different
plants
