उत्तर
The functional megaspore undergoes three successive free nuclear mitotic divisions. These are mitotic divisions where the nucleus divides but cell walls are not immediately formed between the daughter nuclei. This allows the nuclei to move freely within the enlarging megaspore before eventual cell wall formation creates the 7-celled structure.
