Explanation:
capsule prevents the bacteria cell from engulfment by eukaryotic cells
The function of a bacterium's capsule is protection.
The bacterium's capsule encompasses any polysaccharide and / or protein surface layer (including the S-layer of eubacteria), but excludes the S-layers that make up the cell wall of archaebacteria.
The capsule protects the bacteria from phagocytosis, the main defense mechanism used by the host in the presence of capsulated bacteria.
An effective response to defend against this type of bacteria involves the production of antibodies that specifically bind to the capsule, facilitating opsonization and phagocytosis.
Therefore, we can conclude that the bacterium's capsule is generally polysaccharide in nature, it is an outer layer of material, which protects the bacteria from the desiccation of the environment.
