Biology Expert. Regina Bailey is a board-certified registered nurse, science writer and educator. Updated October 12, Key Takeaways Binary fission is the process by which a single cell divides to form two cells that are genetically identical to one another. There are three common bacterial cell shapes: rod-shaped, spherical, and spiral.
Common bacterial cell components include: a cell wall, a cellular membrane, the cytoplasm, flagella, a nucleoid region, plasmids as well as ribosomes. Binary fission as a means of reproduction has a number of benefits, chief among them is the ability to reproduce in high numbers at a very rapid rate.
Since binary fission produces identical cells, bacteria can become more genetically varied through recombination, which involves the transfer of genes between cells. Featured Video.

The course consists of Different groups of cellular microbes evolved and all living organisms, including you, share a common ancestor called LUCA.
The staggering diversity of microbes on Earth today is, in part, due to their ability to replicate rapidly. In this article we consider how the five different groups of microbes do this. Want to keep learning? This content is taken from University of Reading online course,.

Epulopiscium spp. For some of these bacteria, this process appears to be the only way to reproduce. Intracellular offspring development in these bacteria shares characteristics with endospore formation in Bacillus subtilis. In large Epulopiscium spp. Instead of placing the FtsZ ring at the center of the cell, as in binary fission, A Z rings are placed near both cell poles in Epulopiscium.
B Division forms a large mother cell and two small offspring cells. C The smaller cells contain DNA and become fully engulfed by the larger mother cell. D The internal offspring grow within the cytoplasm of the mother cell. E Once offspring development is complete the mother cell dies and releases the offspring.
Our lab studies the mechanisms of intracellular offspring development in Epulopiscium and Metabacterium polyspora. We are interested in what mechanisms are conserved between these unusual reproductive processes and endospore formation.
We hope to gain an understanding of how this novel form of cell reproduction developed over time and how it benefits these intestinal symbionts. Google Tag Manager. Binary Fission and other Forms of Reproduction in Bacteria. Binary Fission Most bacteria rely on binary fission for propagation. Some Unusual Forms of Reproduction in Bacteria: There are groups of bacteria that use unusual forms or patterns of cell division to reproduce. Baeocyte production in the cyanobacterium Stanieria Stanieria never undergoes binary fission.
Budding in bacteria Budding has been observed in some members of the Planctomycetes, Cyanobacteria, Firmicutes a. Intracellular offspring production by some Firmicutes Epulopiscium spp.
