What are characteristics of Eubacteria and Archaebacteria? Eubacteria are usually surrounded by a cell wall. The cell wall contains peptidoglycan, a carbohydrate. It is unicellular and a eukaryote. Archaebacteria are ancestors without peptidoglycan and is unicellular. Explain 3 ways bacteria are important?
