Content: Archaebacteria are spherical, rod shaped, plate like, spirals, flat and even square in shaped. Eubacteria
A single individual archaebacterium ranges from 0.1-15 μ m in diameter. The cell wall of archaebacteria does contain pseudo peptidoglycans. The bacterial cell does consist of cell wall and component structures inside and outside the cell wall. Some component structures include capsules mostly composed of polysaccharides. Some capsules are hetero polysaccharides, for example, capsule of Klebsiella pneumoniae and some are polypeptides e.g. anthracis. Capsules play a significant role in disease causing ability of eubacteria. One more component is the flagella that are thread like, skinny and thin rigid structures, 20 nm wide and around 15 to 20 µ m in length. There is another component structure called Spinae that help bacteria to thrive in harsh environmental conditions like pH, salinity and extreme temperature. Another component is Fimbriae or Pili which are adhesive structures that help bacterial cells to stick to some other bacteria or to a substrate or to some eukaryotic like mould plants and animal cells.
