  2. Fission (biology) - Wikipedia

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

    Binary fission is generally rapid, though its speed varies between species. For E. coli, cells typically divide about every 20 minutes at 37 °C. [11] Because the new cells will, in turn, undergo binary fission on their own, the time binary fission requires is also the time the bacterial culture requires to double in the number of cells it ...

    en.wikipedia.org/wiki/Endosymbiont

    Instead, they replicate via binary fission, a replication process uncoupled from the host cells in which they reside. [ 10 ] [ 11 ] Some human parasites, e.g. Wuchereria bancrofti and Mansonella perstans , thrive in their intermediate insect hosts because of an obligate endosymbiosis with Wolbachia spp. [ 12 ] They can both be eliminated by ...

    en.wikipedia.org/wiki/Marine_microorganisms

    Salt-tolerant archaea (the Haloarchaea) use sunlight as an energy source, and other species of archaea fix carbon; however, unlike plants and cyanobacteria, no known species of archaea does both. Archaea reproduce asexually by binary fission, fragmentation, or budding; unlike bacteria and eukaryotes, no known species forms spores.

  5. Symbiogenesis - Wikipedia

    en.wikipedia.org/wiki/Symbiogenesis

    Mitochondria are regarded as organelles rather than endosymbionts because mitochondria and the host cells share some parts of their genome, undergo division simultaneously, and provide each other with means to produce energy. [40] The endomembrane system and nuclear membrane were hypothesized to have derived from the protomitochondria. [41] [42 ...

  6. Pyrocystis fusiformis - Wikipedia

    en.wikipedia.org/wiki/Pyrocystis_fusiformis

    Bioluminescence occurs when an organism emits light through a chemical reaction [8] with the majority of the world's bioluminescent organisms living in the ocean. [9] The production of bioluminescence by P. fusiformis is thought to be a defense mechanism that startles grazers which would otherwise eat them [5] or to illuminate grazers so that they, in turn may be more visible to their own ...

  7. Euglena - Wikipedia

    en.wikipedia.org/wiki/Euglena

    Euglena reproduce asexually through binary fission, a form of cell division. Reproduction begins with the mitosis of the cell nucleus , followed by the division of the cell itself. Euglena divide longitudinally, beginning at the front end of the cell, with the duplication of flagellar processes, gullet and stigma.

  8. Amitosis - Wikipedia

    en.wikipedia.org/wiki/Amitosis

    Amitosis, also known as karyostenosis, direct cell division, or binary fission, is a form of asexual cell division primarily observed in bacteria and other prokaryotes. This process is distinct from other cell division mechanisms such as mitosis and meiosis , mainly because it bypasses the complexities associated with the mitotic apparatus ...

  9. Autospore - Wikipedia

    en.wikipedia.org/wiki/Autospore

    Cells may use different methods to produce different numbers of autospores or multinucleated autospores; for example, the Dictyochloropsis genus of algae can produce between 4 and 16 autospores when they reproduce. The cell can undergo a multipartition after two rounds of fission as happens in Kirchneriella lunaris. [9]
