In animals, the starting diploid cell is usually called a germ cell and the surviving haploid cells become gametes ( sperm and ova ). (In animals, the female mitotic sequence produces only one ovum; the other three haploid cells become "polar bodies".)

WebThe haploid stage, in which a multicellular haploid gametophyte develops from a spore and produces haploid gametes, is the dominant stage in the bryophyte life cycle. The mature gametophyte produces both male and female gametes, which join to form a … WebMost fungi and algae employ a life-cycle strategy in which the multicellular “body” of the organism is haploid. During sexual reproduction, specialized haploid cells from two individuals join to form a diploid zygote. The zygote immediately undergoes meiosis to form four haploid cells called spores ( Figure 7.2 b ). citizens advice bureau clitheroeWebNow that the haploid sets of chromosomes are located on opposite poles of the cells, cytokinesis may begin. Cytokinesis is the division of the cell cytoplasm into two new daughter cells. Once this process has finished, the cells may enter into interkinesis or a resting period prior to undergoing meiosis II. dick blick clay
