Question

(A) : In angiosperms,microsporogenesis,i.e.,the formation of microspores (or pollen grains),occurs by the meiotic divisions of diploid microspore moth

Vedclass · Accepted Answer

involve meiosis

Vedclass · Answer

(A) : In angiosperms,microsporogenesis,i.e.,the formation of microspores (or pollen grains),occurs by the meiotic divisions of diploid microspore mother cells (or pollen mother cells). Microsporogenesis takes place in the anther.Megasporogenesis,i.e.,the formation of megaspores,occurs by the meiotic divisions of diploid megaspore mother cells. Megasporogenesis takes place in the ovule.Both processes involve meiosis to reduce the chromosome number from diploid $(2n)$ to haploid $(n)$.
