Vedclass · Answer

(B) In the life cycle of plants,gametes are produced by mitosis in haploid plants or by meiosis in diploid plants,but they are always haploid $(n)$ to ensure that fertilization restores the diploid $(2n)$ condition.Similarly,in many plant groups like bryophytes and pteridophytes,spores are produced via meiosis from the sporophyte $(2n)$ and are therefore haploid $(n)$.Thus,both spores and gametes are invariably haploid structures.
