Final answer:
The cell wall of Eubacteria is present and contains peptidoglycan. Eubacteria are divided into two major groups: Gram-positive and Gram-negative.
Step-by-step explanation:
The cell wall of Eubacteria is present and contains peptidoglycan, which is composed of polysaccharide chains cross-linked to peptides.
Eubacteria are divided into two major groups: Gram-positive and Gram-negative, based on their reaction to the Gram stain procedure.
Gram-positive organisms have a thick cell wall, while Gram-negative organisms have a thin cell wall and an outer envelope containing lipopolysaccharides and lipoproteins.
