* Gram-positive bacteria

These form a main group of bacteria. It’s all about the cell wall - in particular, for these little critters, the presence of a thick layer of peptidoglycan and teichoic acids lying outside the plasma membrane. Using the Gram-staining procedure these cells stain purple which you can then check out using the microscope.
