Vedclass · Answer

(C) In plants, $1$ meiotic division produces $4$ functional microspores (pollen grains).To calculate the number of meiotic divisions required to produce $N$ pollen grains, we use the formula: $	ext{Number of meiotic divisions} = \frac{N}{4}$.For $102$ pollen grains, the calculation is $\frac{102}{4} = 25.5$.Since a meiotic division must be a complete process, we cannot have $0.5$ of a division.Therefore, $25$ meiotic divisions would produce $25 	imes 4 = 100$ pollen grains, which is insufficient.Thus, $26$ meiotic divisions are required to produce at least $102$ pollen grains (the $26^{th}$ division will produce the remaining $2$ pollen grains, with $2$ cells degenerating or remaining unused).

To produce $102$ pollen grains, how many meiotic divisions are required?
