(A) For the formation of $140$ angiospermic seeds,$140$ male gametes and $140$ female gametes are required.For the formation of $140$ male gametes,the number of meiotic divisions required is $140 / 4 = 35$.($1$ Microspore mother cell $\xrightarrow{	ext{meiosis}} 4$ microspores)For the formation of $140$ female gametes,the number of meiotic divisions required is $140$.($1$ Megaspore mother cell $\xrightarrow{	ext{meiosis}} 4$ megaspores,where $3$ degenerate and $1$ becomes a functional megaspore)Therefore,the total number of meiotic divisions required is $35 + 140 = 175$.

For the formation of $140$ angiospermic seeds,how many meiotic cell divisions are expected?
