Vedclass · Answer

(A) To form $200$ grains of wheat,we require $200$ pollen grains (male gametes) and $200$ functional megaspores (female gametes).$1$. For male gametes: Each microspore mother cell $(MMC)$ undergoes one reduction division (meiosis) to produce $4$ microspores. Therefore,to produce $200$ microspores,we need $\frac{200}{4} = 50$ reduction divisions.$2$. For female gametes: Each megaspore mother cell $(MMC)$ undergoes one reduction division to produce $4$ megaspores,out of which only one is functional. Therefore,to produce $200$ functional megaspores,we need $200$ reduction divisions.Total reduction divisions = $50 + 200 = 250$.
