Vedclass · Answer

(C) $1$. The development of a mature female gametophyte (embryo sac) starts from a diploid megaspore mother cell $(MMC)$.$2$. The $MMC$ undergoes one meiotic division to produce four haploid megaspores.$3$. Out of these four megaspores,three degenerate and only one functional megaspore develops into the female gametophyte.$4$. This functional megaspore undergoes three successive free nuclear mitotic divisions to form an $8$-nucleated embryo sac.$5$. Therefore,the process requires $1$ meiotic division and $3$ mitotic divisions.

How many meiotic and mitotic divisions need to occur for the development of a mature female gametophyte from the megaspore mother cell in an angiosperm plant?
