\end{figure}
The formation of a mature embryo sac begins with a diploid megaspore mother cell (MMC) in the ovule. This cell undergoes meiosis, producing four haploid megaspores, but only one persists. The surviving megaspore then undergoes three mitotic divisions, resulting in an eight-nucleate embryo sac with seven cells.
