Gametophyte Development & Double Fertilisation
- Microsporogenesis: Formation of haploid microspores from microspore mother cells (MMC) in anther locules.
- Megasporogenesis: Functional megaspore undergoes three rounds of mitosis to form the 8-nucleate, 7-celled mature female gametophyte (Embryo Sac).
- Double Fertilisation: One male gamete fuses with egg cell (Syngamy $\rightarrow$ Zygote); other male gamete fuses with two polar nuclei (Triple Fusion $\rightarrow$ Triploid Endosperm $3n$).
