  2. Cell proliferation - Wikipedia

    en.wikipedia.org/wiki/Cell_proliferation

    Cell division can occur without cell growth, producing many progressively smaller cells (as in cleavage of the zygote), while cell growth can occur without cell division to produce a single larger cell (as in growth of neurons). Thus, cell proliferation is not synonymous with either cell growth or cell division, despite these terms sometimes ...

  3. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    The terminal cell elongates more than the deeper cells; then the production of a lateral bisector takes place in the inner fluid, which tends to divide the cell into two parts, of which the deeper one remains stationary, while the terminal part elongates again, forms a new inner partition, and so on.

  4. Regeneration (biology) - Wikipedia

    en.wikipedia.org/wiki/Regeneration_(biology)

    In one study, two-thirds of the liver was removed and within 24 hours more than half of the liver had undergone hypertrophy. [119] Some sharks can regenerate scales and even skin following damage. Within two weeks of skin wounding, mucus is secreted into the wound and this initiates the healing process. One study showed that the majority of the ...

  5. Cell cycle - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle

    The cell cycle, or cell-division cycle, is the sequential series of events that take place in a cell that causes it to divide into two daughter cells. These events include the growth of the cell, duplication of its DNA ( DNA replication ) and some of its organelles , and subsequently the partitioning of its cytoplasm, chromosomes and other ...

  6. Cellular senescence - Wikipedia

    en.wikipedia.org/wiki/Cellular_senescence

    Somatic cells that have divided many times will have accumulated DNA mutations and would be more susceptible to becoming cancerous if cell division continued. As such, it is becoming apparent that senescent cells undergo conversion to an immunologic phenotype that enables them to be eliminated by the immune system.

Archaea One of the three recognized domains of organisms, the other two being Bacteria and Eukaryota. artificial selection Also called selective breeding.

  8. Tissue growth - Wikipedia

    en.wikipedia.org/wiki/Tissue_growth

    Although different animal tissues grow at different rates and produce organs of very different proportions, the overall growth rate of the entire animal body can be modulated by circulating hormones of the Insulin/IGF-1 family, which activate the PI3K/AKT/mTOR pathway in many cells of the body to increase the average rate of both cell growth and cell division, leading to increased cell ...

  9. Cell growth - Wikipedia

    en.wikipedia.org/wiki/Cell_growth

    Cell growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume. [1] Cell growth occurs when the overall rate of cellular biosynthesis (production of biomolecules or anabolism) is greater than the overall rate of cellular degradation (the destruction of biomolecules via the proteasome, lysosome or autophagy, or catabolism).
