. These bacteria are characterised by a rigid
cell wall. They may either be motile or nonmotile. If motile, they have a
flagellum
A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates.
A microorganism may have f ...
. A typical flagellum consists of a basal body, filament, and hook. The long filament is the organ which helps eubacteria move.
Gram-positive bacteria have a thick proteoglycan layer and take up violet Gram stain (whereas Gram-negative bacteria have a thinner proteoglycan layer which is surrounded by a layer of immune response-inducing lipopolysaccharide, and do not take up Gram stain).
