WebMitosis and meiosis. Cells divide into two different ways to make new cells. Mitosis. Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set. WebOogenesis, ovogenesis, or oögenesis / ˌoʊ.əˈdʒɛnɪsɪs / [1] is the differentiation of the ovum (egg cell) into a cell competent to further develop when fertilized.
