Microvilli Endospores enable bacteria to lie dormant for extended periods, even centuries. The primary function of pili are to attach a bacterial cell to specific surfaces or to other cells. Small, generally microscopic, vibrating appendages lining certain organs, as the air passages of the higher animals, and in the lower animals often covering also the whole or a part of the exterior. structure referred to as basal body, which is made of microtubules. Cilia do not possess a glycocalyx layer whereas Instead of peripherally arranged nice microtubules in a cilium core, the basal body has nine microtubule triplets and has no central microtubules. Both cilia and microvilli are projections in the plasma membrane. The external ends of the pili adhere to a solid substrate, either the surface to which the bacterium is attached or to other bacteria. Pili, Fimbriae and flagella are structures that are found on the cell wall of the bacteria. Endotoxins are lipopolysaccharides found in the cell wall of Gram-negative bacteria, which can induce inflammation and fever as an immune response in higher organisms.
