Vedclass · Answer

(C) In angiosperms like Capsella,one seed is formed from one ovule.For the formation of one seed,one megaspore mother cell undergoes meiosis to produce $4$ megaspores,out of which $3$ degenerate and $1$ becomes functional to form the embryo sac. Thus,$1$ meiotic division is required for the female gametophyte.For the male gametophyte,one microspore mother cell undergoes meiosis to produce $4$ microspores (pollen grains). Thus,$1/4$ meiotic division is required for one pollen grain.Total meiotic divisions required for $1$ seed = $1$ (for female) + $1/4$ (for male) = $5/4$ divisions.For $200$ seeds,total meiotic divisions = $200 	imes (5/4) = 250$.
