उत्तर
The haploid functional megaspore undergoes three successive free nuclear mitotic divisions to reach the 8-nucleate stage: Mitosis I produces 2 nuclei, Mitosis II produces 4 nuclei, and Mitosis III produces 8 nuclei. Each division doubles the number of nuclei while maintaining the haploid ploidy level.
