Question : How many reduction division are necessary for the formation

1.	Question : How many reduction division are necessary for the formation of 200 grains of wheat
Answer» 250 150 200 360 Solution :For the FORMATION of 10 grams of WHEAT 100 pollen GRAINS and 100 megaspores are required . Each micropore mother cell produces 4 microspores (pollen grains) as a result of reduction division. Hene for the formation of 100 pollen grains. `(100)/(4)=25PMC` are needed and eachwill undergo one reduction division. Each megaspore motehr cell will produce 4 megaspores in which one become functional and other three degenerate. thus each MMC produces one megaspore. So 100 MMC are required to produce 100 megaspores. Total number of reduction divisions to produce 100 grains is 100+25=125
