Vedclass · Answer

(B) In angiosperms,one meiotic division produces $4$ microspores (pollen grains) and $1$ functional megaspore (embryo sac). For the formation of $1$ seed,$1$ male gamete and $1$ female gamete are required. In the family Cyperaceae,the formation of $1$ seed requires $1$ meiotic division for the male gamete and $1$ meiotic division for the female gamete (since only $1$ out of $4$ megaspores is functional,but in Cyperaceae,all $4$ microspores are functional,yet the female side requires $1$ meiosis per seed). Total meiotic divisions = $n + n/4$ is the standard formula for general angiosperms,but for Cyperaceae,the female side requires $1$ meiosis per seed $(100)$ and the male side requires $100/4 = 25$ meiosis. Total = $100 + 25 = 125$.

What is the number of meiotic divisions required to produce $100$ seeds in the family Cyperaceae?
