Vedclass · Answer

(D) During megasporogenesis,one megaspore mother cell $(MMC)$ undergoes meiosis to produce $4$ haploid megaspores.Therefore,$100$ $MMC$s will produce $100 	imes 4 = 400$ megaspores $(a = 400)$.In a typical angiosperm,out of the $4$ megaspores,$3$ degenerate $(b)$ and only $1$ remains functional $(c)$.For $100$ $MMC$s,the number of degenerating megaspores is $100 	imes 3 = 300$ $(b = 300)$.The number of functional megaspores is $100 	imes 1 = 100$ $(c = 100)$.

If $100$ megaspore mother cells undergo meiosis,then how many megaspores are formed $(a)$,how many degenerate $(b)$,and how many remain functional $(c)$?
