By: Dan Barber, Ashley Fitzgerald, Corrine Stiles, Mitchell Workman They are unicellular. They are prokaryotic. They can be autotrophs, heterotrophs, or decomposers. Most have thick cell walls made of peptidoglycan and multiple flagellae. “Eu” is Greek for genuine and when used in “eubacteria” it means special prokaryote. Viruses are apart of the Eubacteria Kingdom because they are symbiotic and need to bond to a host (see homeostasis). They are two types of eubacteria; Gram-positive and Gram-negative. There are three important phylum's in this kingdom; Cyanobacteria, Spirochetes and Proteobacteria. >Gram positive eubacteria have a gram stained cell wall that is very thick. >Gram negative eubacteria have an unstained gram cell wall that is typically thin. Eubacteria are prokaryotic and are without a nucleus. They are all unicellular. Eubacteria have generally thick cell walls depending on how they are stained. Eubacteria can have a wide number of flagellae that help them move eat and interact. Eubacteria are unicellular and do not develop past a cell they do not make up tissue, organs, etc.
