According to Gram-staining, bacteria are divided into Gram-positive or Grma-negavtive bacteria. Gram-staing mostly differentiate the architecture of cell wall and gives a positive or negative result. The characteristic features of Gram-positive bacteria are
- The cell wall is made up of single-layered (capsule)and smooth in nature.
- Gram-positive bacteria possess flagella and the basal body rings supports it.
- Mesosome (infolding of plasma membrane) is prominantly observed in the Gram-positive bacteria.
