Are eubacteria unicellular or multicellular? How many cells do they have? The eubacteria number of cells is only one. They are single prokaryotic cells. There is no such thing as eukaryotic bacteria. The structures found in eubacterial cells are either external or internal to the cell wall.
Structures external to the cell wall may be flagella, fimbriae, axial filaments, glycocalyx, or pill. Each of these structures has its distinctive function where some eubacteria have flagella to facilitate their movement.
Flagella are long filaments that facilitate the mobility of bacteria. Flagella consist of three main parts: a portion consisting of flagellin protein called the filament (ie. the long outermost part), the middle hook, and the basal body that attaches the bacterial plasma membrane and cell wall.
Fimbriae and pili are hairlike structures similar to flagella but thinner. Pili or pilus are thin projections used for conjugation between bacteria for reproduction after the bacteria are brought together by pili, the DNA moves from one cell to another so new features as antibiotic resistance are transferred between cells Glycocalyx surrounds some eubacterial cells. It is a viscous polymer composed of polypeptides or polysaccharides and functions to protect the bacteria. It is commonly known as the capsule. The capsule is considered to be one of the virulence factors of some bacteria since it enables the bacteria to resist phagocytosis by the immune system. Glycocalyx coat can also help bacteria to attach firmly to the host cell such as Vibrio cholera that produces glycocalyx to attach to the intestinal cells.
