In plants, a rigid cell wall is formed at the middle of the parent cell, separating it into two. The contractions of actin fibers result in the pinching of the parent cell into two daughter cells. Telophaseĭuring telophase, sister chromatids arrive at the two opposite poles and new nuclear membranes are formed around the two daughter nuclei.Īfter undergoing the nuclear division, the division of the cytoplasm or the cytokinesis begins with the arrangement of actin fibers around the center of the cell in animals. The separated sister chromatids begin to move towards the opposite poles of the cell. Anaphaseĭuring anaphase, sister chromatids are separated from their centromeres. The individual chromosomes are aligned along the cell equator with the help of the mitotic spindles, ensuring the proper segregation of sister chromatids into the two daughter cells. Microtubules of the mitotic spindle attach to the kinetochore proteins. The nuclear membranes are dissolved and the kinetochore proteins are formed in the centromeres of chromosomes during the prometaphase. Since the two centrioles move to opposite poles, the mitotic spindle begins to form. The chromatin in the nucleus is condensed and become visible as chromosomes during prophase. The prophase, prometaphase, metaphase, telophase, and the anaphase are the stages of mitosis. DNA replication, protein synthesis, and the synthesis of organelles occur during interphase. The cell’s highest rate of metabolic activity can be observed during the interphase. The interphase is composed of G 1, S and G 2 stages. Typically, a diploid cell which completes its interphase undergoes mitosis. The mitosis is a process of nuclear division, which is always followed by the division of cytoplasm, cytokinesis. Mitosis is seen in ordinary tissue growth and repair, increasing the somatic cell number of the body. Mitosis is a type of cell division, which produces two daughter cells identical to the parent cell. Key Terms: Anaphase, Anaphase I, Anaphase II, Cell Division, Daughter Cells, Diploid, Haploid, Gametes, Metaphase, Metaphase I, MetaphaseII, Meiosis, Mitosis, Parent Cells, Prometaphase, Prophase, Prophase I, Prophase II, Somatic Cells, Telophase, Telophase I, Telophase II What are the Similarities Between Mitosis and Meiosis Mitosis occurs in somatic cells in the body of multicellular organisms and meiosis only occurs in germ cells. By mitosis, four haploid gametes are produced. By mitosis, two identical daughter cells are produced. Both mitosis and meiosis start with diploid parent cells. Meiosis occurs only in animals, plants, and fungi. Mitosis occurs in all living organisms on earth except viruses. Occurs in germ cells (produces sex cells) 3.Mitosis and meiosis are the two types of mechanisms involved in cell division and reproduction of all multicellular organisms. 5.1 cell division and the cell cycle lesson 5.1: Start Studying Mitosis Vs Meiosis Review Worksheet Questions.
