1. Anther
2. Quadripartition of the microspore mother cell.
3. Pollen grain.
4. Development and structure of the ovule.
5. Origin and extent ,of the sporogenous tissue in the ovule.
6. Megasporogenesis and development of the embryo sac.
7. Form and organisation of the mature embryo sac.
8. Fertilisation.
