  2. Mitosis - Wikipedia

    en.wikipedia.org/wiki/Mitosis

    For example, starfish regenerate lost arms through mitosis. Asexual reproduction: Some organisms produce genetically similar offspring through asexual reproduction. For example, the hydra reproduces asexually by budding. The cells at the surface of hydra undergo mitosis and form a mass called a bud. Mitosis continues in the cells of the bud and ...

  3. 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).

  4. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    Cell division in prokaryotes (binary fission) and eukaryotes (mitosis and meiosis). The thick lines are chromosomes, and the thin blue lines are fibers pulling on the chromosomes and pushing the ends of the cell apart. The cell cycle in eukaryotes: I = Interphase, M = Mitosis, G 0 = Gap 0, G 1 = Gap 1, G 2 = Gap 2, S = Synthesis, G 3 = Gap 3.

  5. Multinucleate - Wikipedia

    en.wikipedia.org/wiki/Multinucleate

    For example, slime molds have a vegetative, multinucleate life stage called a plasmodium. [ 1 ] Multinucleate cells, depending on the mechanism by which they are formed, can be divided into [ 2 ] [ 3 ] " syncytia " (formed by cell fusion ) or " coenocytes " (formed by nuclear division not being followed by cytokinesis ).

  6. Cell cycle - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle

    The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.

  7. Regeneration (biology) - Wikipedia

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

    Sunflower sea star regenerates its arms. Dwarf yellow-headed gecko with regenerating tail. Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. [1]

    Since 2010, scientists have known that the Y chromosome is rapidly evolving in humans, but a new study shows that the same can be said across all Great Apes—the closest relatives to humans.

  9. Mitogen - Wikipedia

    en.wikipedia.org/wiki/Mitogen

    Mitogens can be either endogenous or exogenous factors. Endogenous mitogens function to control cell division is a normal and necessary part of the life cycle of multicellular organisms. For example, in zebrafish, an endogenous mitogen Nrg1 is produced in response to indications of heart damage. When it is expressed, it causes the outer layers ...
