Bacteria are unicellular structures that are generally less than 5 m, which reproduce asexually through a process called binary fission, which are constituted by a set of components that form the outside and inside of the prokaryote microorganism. Show a casing surrounding externally Gram positive and Gram negative bacteria, this structure has an arrangement inside out beginning with the cytoplasmic membrane, cell wall and an extracellular substance called glycocalyx, in turn, inside the bacteria present the cytoplasm, ribosomes and chromosomal DNA structures that are permanent and essential for the life of the bacteria elements. There are also other components called optional elements or floating structures that differ in different organisms, and which may or may not be present, among which are the flagella, fimbriae or pili which are called appendages of bacteria, such as the capsule, endospores and cytoplasmic inclusions.
