Fusion of an egg and a sperm creates a zygote and restores the 2 n ploidy level. The zygote divides mitotically to form the embryo, which then develops into the sporophyte. Eventually the sporophyte produces sporangia, which…

WebThis phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations. In the life cycle, change of ploidy level from diploid (2n) to haploid (n) is brought about by meiosis while fertilization change the ploidy level from haploid (n) to diploid (2n). WebThe diploid sporophyte has a structure called sporangium. The sporangium undergoes meiosis and forms haploid spores. The spore develops into a gametophyte which is haploid in nature. The gametophyte has the …
