  2. List of longest-living organisms - Wikipedia

    en.wikipedia.org/wiki/List_of_longest-living...

    The definition of "longest-living" used in this article considers only the observed or estimated length of an individual organism's natural lifespan – that is, the duration of time between its birth or conception, or the earliest emergence of its identity as an individual organism, and its death – and does not consider other conceivable ...

  3. Valonia ventricosa - Wikipedia

    en.wikipedia.org/wiki/Valonia_ventricosa

    The surface of the cell shines like glass when clean due to being extremely smooth with no texture. Valonia ventricosa is among the largest known single-celled organisms. Its thallus consists of a thin-walled, tough, multinucleate cell with a diameter that ranges typically from 1 to 4 centimetres (0.4 to 1.6 in), although it may achieve a ...

    en.wikipedia.org/wiki/Drosophila_bifurca

    Drosophila bifurca is a species of fruit fly.Males of this species are known to have the longest sperm cells of any organism on Earth—5.8 cm long when uncoiled, over twenty times the entire body length of the male.

  6. HeLa - Wikipedia

    en.wikipedia.org/wiki/HeLa

    HeLa cells are rapidly dividing cancer cells, and the number of chromosomes varies during cancer formation and cell culture. The current estimate (excluding very tiny fragments) is a "hypertriploid chromosome number (3n+)", which means 76 to 80 total chromosomes (rather than the normal diploid number of 46) with 22–25 clonally abnormal ...

  7. Acetabularia - Wikipedia

    en.wikipedia.org/wiki/Acetabularia

    Acetabularia is a genus of green algae in the family Polyphysaceae. [4] Typically found in subtropical waters, Acetabularia is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology. [5]

  8. Immortalised cell line - Wikipedia

    en.wikipedia.org/wiki/Immortalised_cell_line

    An immortalised cell line is a population of cells from a multicellular organism that would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular senescence and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro. The mutations required for immortality can occur ...

  9. Cell (biology) - Wikipedia

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

    The cell on the left is going through mitosis and its chromosomes have condensed. Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes, and is the place where almost all DNA replication and RNA synthesis (transcription) occur.
