Vedclass · Answer

(A) In angiosperms like $Capsella$,each seed is formed from a fertilized ovule. One meiotic division in a microspore mother cell produces $4$ functional pollen grains. One meiotic division in a megaspore mother cell produces $1$ functional egg cell (as $3$ degenerate). To produce $1$ seed,we need $1$ male gamete and $1$ female gamete. For $40$ seeds,we need $40$ male gametes and $40$ female gametes. Number of meiotic divisions for male gametes = $40 / 4 = 10$. Number of meiotic divisions for female gametes = $40 / 1 = 40$. Total meiotic divisions = $10 + 40 = 50$.

The number of meiotic divisions required to produce $40$ seeds in $Capsella$ is:
