What is cell growth?

Cell Growth

The term cell growth is used in the contexts of cell development and cell division (reproduction). When used in the context of cell division, it refers to growth of cell populations, where one cell (the "mother cell") grows and divides to produce two "daughter cells" (M phase). When used in the context of cell development, the term refers to increase in cytoplasmic and organelle volume (G1 phase), as well as increase in genetic material before replication (G2 phase).

Famous quotes containing the words growth and/or cell:

    Unlimited economic growth has the marvelous quality of stilling discontent while maintaining privilege, a fact that has not gone unnoticed among liberal economists.
    Noam Chomsky (b. 1928)

    Women have no wilderness in them,
    They are provident instead,
    Content in the tight hot cell of their hearts
    To eat dusty bread.
    Louise Bogan (1897–1970)
