Vedclass · Answer

(A) In angiosperms,the development of the female gametophyte (embryo sac) involves the formation of a megaspore mother cell $(MMC)$.Each $MMC$ undergoes a single meiotic division to produce $4$ megaspores.Out of these $4$ megaspores,$3$ degenerate and only $1$ functional megaspore develops into a female gametophyte (embryo sac).Therefore,to produce $1$ female gametophyte,$1$ meiotic division is required.To produce $101$ female gametophytes,$101$ meiotic divisions are required.
