Vedclass · Answer

(B) In organisms like $Ulothrix$,$Spirogyra$,and $Chlamydomonas$,the dominant plant body is haploid $(n)$.These organisms reproduce sexually by the fusion of gametes to form a diploid zygote $(2n)$.Since the plant body is haploid,the zygote cannot undergo mitosis to form the plant body.Therefore,the zygote undergoes meiosis (reduction division) to produce haploid spores $(n)$,which then germinate to form new haploid individuals.Thus,meiosis occurs during the germination of the zygote.
