One possible strategy for reproduction would be to produce a small reproductive cell that would have the minimal requirements for independent growth. The mother cell in this instance would not commit so much of its resources to reproduction as would be required if the daughter cell were the same size as the parent cell. Two examples of cell division processes, budding and baeocyte production, are known in bacteria that result in the production of cells that are smaller than the parent. In addition, some bacteria produce special hardy cells referred to as endospores, cysts, or exospores that may be smaller than the parent cell. Buds and Baeocytes.
Many bacteria produce buds.
Some Pleurocapsaen cyanobacteria undergo multiple fission to produce small cells referred to as baeocytes. Endospores, Cysts, and Exospores. Endospores are special survival cells produced by some gram-positive bacteria, particularly those that live in sediments, soil, and rock environments. The classical genera Bacillus and Clostridium are best known for endospore production, but others such as Sporo Bacillus also are known. The endospore contains DNA, ribosomes, and several layers of wall material referred to as a coat.
