Mitosis duplication of cells through asexual reproduction Mitosis is not synonymous with cell division What organisms go through mitosis? single-celled prokaryotes and single-celled eukaryotes Where does mitosis take place? somatic cells Product of mitosis 2 identical diploid daughter cells Purpose of Mitosis growth, repair, and asexual reproduction Cell Division process by which a parent cell duplicates its genetic material and then divides into two similar cellsCytokinesis the duplication and division of the cytoplasm in a cell Product of cytokinesis new cell walls or plasma membranes for each daughter cell When does cytokinesis occur? telophase Mitosis without cytokinesis results in cells with more than one nucleus Example of mitosis without cytokinesis plasmodium/slime mold Ploidy number of the kinds of chromosomes found in a species What is the ploidy for humans? diploid and 46 chromosomes (23 pairs) What is the ploidy for bacteria? diploid and 46 chromosomes Haploid (n) 1 set of each kind of chromosomeDiploid (2n) 2 sets of each kind of chromosome (paternal and maternal) You should do a ploidy count when the mitotic or meiotic stages have been completed Most cells in the body are diploid Meiosis only occurs in diploid cells Germinal Cells cells involved directly in the process of reproduction Female germinal cells egg cell Male germinal cells sperm cell Somatic Cells body cells that are not specialized for reproductionSomatic cells are diploid Homologous Chromosomes pairs of
