    Study Notes

    Cell Division Mechanisms

    • The primary function of mitosis is to produce two daughter cells that are genetically identical to the parent cell.
    • Mitosis is the type of cell division that typically contributes to asexual reproduction in unicellular organisms.
    • Meiosis is significant because it allows for genetic variation by producing gametes with unique combinations of chromosomes, essential for sexual reproduction.
    • The failure of cell division mechanisms can result in genetic abnormalities, cancer, and birth defects.
    • Cancer cells become malignant when they gain the ability to invade and metastasize to other parts of the body.
    • The cell cycle is significant because it allows cells to grow, replicate, and divide in a controlled manner, ensuring proper tissue development and maintenance.
    • Meiosis contributes to genetic diversity by producing gametes with unique combinations of chromosomes, which increases the likelihood of genetic variation in offspring.
    • The failure of cell division mechanisms can result in genetic abnormalities, cancer, and birth defects.
    • Cell division contributes to asexual reproduction in unicellular organisms when it occurs in a asymmetric manner, producing a new individual that is genetically identical to the parent cell.
