WebPlants use mitosis to grow as sporophytes, and to grow and produce eggs and sperm as gametophytes; so they use mitosis for both haploid and diploid cells (as well as for all other ploidies). In meiosis, the starting nucleus is always diploid and the daughter nuclei that result are haploid. WebWhen gametes are produced, the maternally and paternally inherited chromosomes are crossed over and distributed randomly into four different gametes. Although these genomes are mostly identical, there is enough var Continue Reading 3 Dr.Raajasiri Iyengar In love with Biology since five years!! Author has 81 answers and 549.1K answer views 6 y

WebFormation of Gametes Meiosis, a two-step process gives rise to gametes. The outcome of this process is 4 haploid daughter cells, each of which contains only one set of chromosomes. Through the process of fertilization (which can either be external or internal), they unite forming the zygote. WebThe haploid multicellular plants (or algae) are called gametophytes, because they make gametes using specialized cells. Meiosis is not directly involved in making the gametes in this case, because the organism is already a haploid.
