Vedclass · Answer

(A) $1$. The process begins with a diploid megaspore mother cell $(MMC)$.$2$. The $MMC$ undergoes one meiotic division (meiosis) to produce four haploid megaspores.$3$. Three of these megaspores degenerate,and one functional megaspore develops into the female gametophyte (embryo sac).$4$. The nucleus of the functional megaspore undergoes three successive free nuclear mitotic divisions to form an $8$-nucleated structure.$5$. These nuclei then organize into the $7$-celled,$8$-nucleated mature embryo sac.$6$. Therefore,the formation requires $1$ meiotic division and $3$ mitotic divisions.

How many meiotic and mitotic divisions are required for the formation of a fully mature female gametophyte (embryo sac) from a megaspore mother cell?
