In plants, both haploid and diploid cells can divide bymitosis. This ability leads to the formation of differentplant bodies haploid and diploid. The haploid plantbody produces gametes by mitosis. This plant bodyrepresents a gametophyte. Following fertilisation the zygote also divides by mitosis to produce a diploidsporophytic plant body.
Haploid spores are producedby this plant body by meiosis. These in turn, divide bymitos is to form a haploid plant body once again. Thus,during the life cycle of any sexually reproducing plant,there is an alternation of generations between gameteproducing haploid gametophyte and sporeproducingdiploid sporophyte.
