Vedclass · Answer

(D) $1$. The megaspore mother cell $(MMC)$ undergoes a single meiotic division to produce four haploid megaspores.$2$. Out of these four,three degenerate,and one functional megaspore develops into the embryo sac.$3$. The nucleus of the functional megaspore undergoes three successive free nuclear mitotic divisions to form $8$ nuclei.$4$. These nuclei then organize into a $7$-celled,$8$-nucleate mature embryo sac.$5$. Therefore,the process requires $1$ meiotic division and $3$ mitotic divisions.

How many meiotic and mitotic divisions are required for the formation of a mature embryo sac from a megaspore mother cell in flowering plants?
