Eubacteria
Examples
Mycobacterium tuberculosis (bottom left), Yersinia pestis (bottom middle), Streptococcus pneumoniae (bottom right)
Peptidoglycan
On eubacteria's cell wall they have peptidoglycan. Peptidoglycan is made of disaccharides and peptide fragments. This layer of peptidoglycan helps protect the bacteria from antibiotics. Bacteria with a thick layer of peptidoglycan are called gram positive, while bacteria with a thin layer are call gram negative. The thicker the layer of peptidoglycan the more resistant to antibiotics the bacteria will be.
Evolutionary Milestones
Eubacteria have passed no evolutionary milestones.
Habitat
Eubacteria live in normal temperatures and resources. These bacteria can be found almost everywhere, except extreme environments. They can live with or without oxygen.

Anatomical/Structural Features
How do they acquire nutrients
Eubacteria are both autotrophic and heterotrophic.
What do they eat
Some eubacteria use organic molecules for food, others use the sun's light to make their own food, and others make organic molecules for their food.
What eats them
Eubacteria is eaten ny animal-like protist.
Symmetry
lack symmetry
Mobility
Eubacteria move by using their flagella. A flagella is a whip-like structure that the cell uses to move toward light, higher oxygen concentration, or chemicals such as sugar or amino acids that they need to survive.
Reproduction
Eubacteria reproduce by binary fission. Binary fission is an asexual process that starts when the cell's chromosomes replicate and then move to opposite ends of the cell. When this happens the cell elongates. Finally a new piece of plasma membrane and cell wall forms dividing the cell into two identical cells.
Development
Development includes seven characteristics of life.
Other Information
Eubacteria can go through a process called through conjugation, which is when two cells exchange genetic info by attaching their pili together. This creates more genetic diversity among the population.
