    Binary or bipartition fission is a form of asexual reproduction that takes place in archaea and bacteria. It consists of the duplication of DNA, continuation of the division of the cytoplasm (cytoclasis), giving rise to two daughter cells. Instead, multiple fusion is a type of asexual reproduction, where a stem cell divides itself repetitively or sequentially into fragments of daughter cells called beocytes or nanocytes.

    Contrary to binary fission, multiple fission is not accompanied by an increase in cytoplasmic volume, and each round of division produces sequentially smaller descending cells, causing the cells to be seen in irregularly sized arrangements. Eventually the extracellular matrix tears and the daughter cells or beocytes are released. You don't have to know what factors trigger this cycle, but environmental cues play a role. This process is not yet characterized at the genetic or molecular level.


    Organisms that carry out multiple fission include cyanobacteria of the order Pleurocapsales, some Proteobacteria like Bdellovibrio only under certain special conditions, Actinobacteria like Actinoplanes produce offspring by multiple fission of filaments within the sporangium.

    That is why if they would reproduce by means of multiple fission, the bacteria would require more environmental conditions, and would depend a lot on external factors.

    Once this ideal climax has been achieved, the bacteria begin their reproduction and it could even be faster than binary fission.
