(A) Wheat is an angiosperm plant. In this plant,$80$ grains (seeds) are produced by the fertilization between $80$ male and $80$ female gametes.To produce $80$ male gametes (pollen grains),$20$ meiotic divisions are required in microspore mother cells,as each meiosis produces $4$ microspores.To produce $80$ female gametes (egg cells),$80$ meiotic divisions are required in megaspore mother cells,because in angiosperms,after meiosis in a single megaspore mother cell,$4$ megaspores are formed,but only $1$ survives while the other $3$ degenerate.Thus,the total number of meiotic divisions is $20 + 80 = 100$.
