In this chapter, we’ll learn about the detailed structure of the flower. After that, we’ll deal with the pre-fertilisation structure and events (Stamen, microsporangium, Pollen grain, Pistil, megasporangium and Embryo sac). Then we’ll deal with pollination, pollen-pistil interaction and artificial hybridisation. Then we will deal with double fertilisation. After that, we’ll deal with the post-fertilisation structure and events (endosperm, embryo, seeds). Finally, we’ll learn about apomixis and polyembryony.
