Haploid having one set of chromosomes (1n)
Does Haploid undergo meiosis or mitosis? meiosis
Does diploid undergo meiosis or mitosis? Both
Meiosis type of nuclear division in which one diploid parent cell produces four haploid cells
Mitosis type of nuclear division in eukaryotic cells that results in two daughter cells genetically identical to the parent cell
Are daughter cell of mitosis, haploid or diploid? depends on the parent cell

gametes haploid egg and sperm fuse (fertilization) to produce a diploid zygote that grows into a diploid sporophyte through mitosis
Alternation of Generation plants alternate between two multicellular stages
Two stages of Alternation of Generation gametophyte generation (gamete-producing plant), sporophyte generation (spore producing plant)
what does the gametophyte generation produce Haploid produces haploid gametes through mitosis
what does the sporophyte generation produce Diploid produces haploid spores through meiosis
Spores Germinate cells divide by mitosis and develop into a haploid gametophyte
