It's main function is in cell division. FtsZ proteins can be viewed as the microtubule spindle apparatus analog that are present in eukaryotes.

Does bacteria have microtubules?
Bacteria do not have microtubules in an eukaryotic sense since they do not have tubulin. However, they do have tubulin homologue FtsZ protein that form structures and perform functions similar to microtubules in eukaryotes. Sometimes these structures are referred to as 'bacteria microtubules'.
What are the basic steps in asexual reproduction among bacteria?
They reproduce by Process called BINARY FISSION Binary fission begins with DNA replication. DNA replication starts from an origin of replication, which opens up into a replication bubble (note: prokaryotic DNA replication usually has only 1 origin of replication, whereas eukaryotes have multiple origins of replication). The replication bubble separates the DNA double strand, each strand acts as template for synthesis of a daughter strand by semiconservative replication, until the entire prokaryotic DNA is duplicated. After this replicational process, cell growth occurs. Each circular DNA strand then attaches to the cell membrane. The cell elongates, causing the two chromosomes to separate. Cell division in bacteria is controlled by the FtsZ, a collection of about a dozen proteins that collect around the site of division. There, they direct assembly of the division septum. The cell wall and plasma membrane starts growing transversely from near the middle of the dividing cell. This separates the parent cell into two nearly equal daughter cells, each having a nuclear body. The cell membrane then invaginates (grows inwards) and splits the cell into two daughter cells, separated by a newly grown cell plate.
How does streptococcus pneumonia?
S. pneumoniae reproduces through a mechanism known as binary fission. It involves the cell copying it's genetic material then splitting in two by a ring of proteins called the FTsZ ring.

What do other organisms have that prokaryotes don't?
Prokaryotes differ with other organisms in they don't have definite nucleus, nuclear envelop is absent. nucleolus is absent. no mitosis instead they show amitosis mediated by divisomes ( septasome ) which include the protein FtsZ ( filaments that are temperature sensitive Z ).
Are microtubules prokayote or eykaryote?
Microtubules (actin and tubulin) are cytoskeleton of eukaryote (and not prokaryote). Prokaryote do have cytoskeleton system such as FtsZ.
How does staph infection reproduce?
it reproduces when people spread it to one another. by sharing things and by coughing or sneezing and especially for not covering your mouth. it gets on one spot and then starts doubling.
What are the two ways that archaea can reproduce?
Archaea reproduce asexually by binary or multiple fission, fragmentation, or budding; meiosis does not occur, so if a species of archaea exists in more than one form, all have the same genetic material. Cell division is controlled in a cell cycle after the cell's chromosome is replicated and the two daughter chromosomes separate, the cell divides. Details have only been investigated in the genus Sulfolobus, but here that cycle has characteristics that are similar to both bacterial and eukaryotic systems. The chromosomes replicate from multiple starting-points using DNA polymerases that resemble the equivalent eukaryotic enzymes. However, the proteins that direct cell division, such as the protein FtsZ, which forms a contracting ring around the cell, and the components of the septum that is constructed across the center of the cell, are similar to their bacterial equivalents.Both bacteria and eukaryotes, but not archaea, make spores. Some species of Haloarchaea undergo phenotypic switching and grow as several different cell types, including thick-walled structures that are resistant to osmotic shock and allow the archaea to survive in water at low salt concentrations, but these are not reproductive structures and may instead help them reach new habitats.

How do eukaryotic cells divide by binary fission?
Binary fission, or prokaryotic fission, is the form of asexual reproduction and cell division used by all prokaryotes, some protozoa, and some organelles within eukaryotic organisms. This process results in the reproduction of a living prokaryotic cell by division into two parts which each have the potential to grow to the size of the original cell. Mitosis and cytokinesis are not the same as binary fission; specifically, binary fission cannot be divided into prophase, metaphase, anaphase, and telophase because prokaryotes have no nucleus and no centromeres. The ability of some multicellular animals, such as echinoderms and flatworms, to regenerate two whole organisms after having been cut in half, is also not the same as binary fission. Neither is vegetative reproduction of plants. Binary fission begins with DNA replication. DNA replication starts from an origin of replication, which opens up into a replication bubble (note: prokaryotic DNA replication usually has only 1 origin of replication, whereas eukaryotes have multiple origins of replication). The replication bubble separates the DNA double strand, each strand acts as template for synthesis of a daughter strand by semiconservative replication, until the entire prokaryotic DNA is duplicated.

The cell wall and plasma membrane starts growing transversely from near the middle of the dividing cell. This separates the parent cell into two nearly equal daughter cells, each having a nuclear body.[1] The cell membrane then invaginates (grows inwards) and splits the cell into two daughter cells, separated by a newly grown cell plate. Use by eukaryotic organelles Eukaryotic organelles such as mitochondria, chloroplasts, and peroxisomes also reproduce within the eukaryotic cell by binary fission. How they are allotted to one descendant cell or the other during mitosis and cytokinesis is not yet clear
