Question

microspores and megaspores are considered haploid in nature? True or False

Answer 1

Yes, the microspore and the megaspore are considered haploid in nature. During microsporogenesis( development of anther), the primary sporogenous cells, divide mitotically to form sporogenous cells, which later differentiate into microspore mother cells. These microspre mother cells further divide meiotically to produce the haploid Micropsores. Similarly during megasporogenesis, the megaspore mother cell forms haploid megaspores by meiosis. Meiosis being a reduction division process results in half the number of complete diploid chromosomes i.e haploid number in the microspore as well as megaspore.
