    Study Notes

    Cell Division and Growth

    • Mitosis is the process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
    • Mitosis occurs in somatic cells (non-reproductive cells) and is involved in tissue renewal and growth.

    Stages of Mitosis

    • During prophase, chromosomes condense and become visible, and spindle fibers form.
    • During metaphase, all chromosomes line up along the plate.
    • During anaphase, sister chromatids separate and move to opposite poles of the cell.
    • During telophase, chromosomes uncoil and become diffuse, and the nuclear envelope reforms.

    Characteristics of Mitosis

    • Mitosis involves the production of two diploid daughter cells, each with the same number of chromosomes as the parent cell.
    • Mitosis occurs in somatic cells, such as skin cells and muscle cells.

    Meiosis

    • Meiosis is the process of cell division that results in four haploid daughter cells, each with half the number of chromosomes as the parent cell.
    • Meiosis occurs in reproductive cells (gametes) and is involved in the production of sex cells (sperm and egg cells).
    • During meiosis, crossing over occurs in prophase I, allowing for genetic recombination and increased genetic diversity.

    Characteristics of Meiosis

    • Meiosis involves two rounds of cell division, resulting in four haploid daughter cells.
    • Meiosis produces genetically different haploid cells, increasing genetic diversity.

    Comparison of Mitosis and Meiosis

    • Mitosis produces two diploid daughter cells, while meiosis produces four haploid daughter cells.
    • Mitosis occurs in somatic cells, while meiosis occurs in reproductive cells.
    • Mitosis does not involve crossing over, while meiosis does.

    Functions of Mitosis and Meiosis

    • The purpose of mitosis is to produce new cells for growth and tissue renewal.
    • The purpose of meiosis is to produce genetically diverse sex cells (sperm and egg cells) for sexual reproduction.
