CharacteristicsDepending on species - nutrition intake may
be by absorption, photosynthesis, or chemosynthesis.
Asexual reproductionShape:
Round or Spherical or Oval Shaped: Ex. Micrococcus, Streptococcus and Sarcina
Rod Shaped: Ex. Lactobacillus, Bacillus and Pseudomonas
Spiral or Comma Shaped: Ex. Vibrio, Camphilovextor and Triponema

Characteristics cont.General structure
Rigid cell wall to hold in organelles: made up of amino acids and a sugar chain
Some have a cell membrane outside cell wallNo nucleus
Cell walls contain peptidoglycan

PHYLAThe Eubacteria kingdom consists of the phyla
: • Cyanobacteria
• Spirochaete
• Proteobacteria

CyanobacteriaPhotosynthetic- contain chlorophyll pigmentFound in ocean and on landThick cell wall and no flagellaCommonly called blue-green algaeConsidered the ancestors of present day
chloroplastsGrow in coloniesCan manufacture their own food through
photosynthesis

Spirochaete• Helically coiled cells• Flagella allow movement in a twisting motion• Most are anaerobic• Some may cause dangerous diseases

ProteobacteriaMostly anaerobic organismsSome can photosynthesizeSome are nitrogen fixatingMost have flagella but those who don’t move
by glidingSome can be helpful while others cause
disease

Eubacteria vs. ArchaebacteriaArchaebacteria:
“ancient bacteria”. Live in extreme environments (such as deep
sea volcanic vents) while eubacteria live in more common environments.
Archaebacteria cell walls also don’t contain peptidoglycan while those of eubacteria do.

Eubacteria vs. ProtistsProtists:
Eubacteria are Prokaryotes and have no nuclear membrane. Protists are Eukaryotes and have a nuclear membrane.
Protists need water while Eubacteria are able to survive almost anywhere
Eubacteria can only reproduce asexually while protists can reproduce either sexually or asexually.

Eubacteria vs. fungi and plantaeFungi:
Fungi are multicellular while eubacteria are unicellular
Fungi are eukaryotic and eubacteria are prokaryotic
Fungi reproduce by spores and eubacteria reproduce by binary fission
Plantae:Plants are eukaryotic, multicellular and have a
cell wall made of celluloseEubacteria are prokaryotic, unicellular and
have a cell wall containing peptidoglycan

Eubacteria vs. AnimaliaAnimalia:
Animals are multicellular, eukaryotic, and reproduce sexually.
Eubacteria are unicellular, prokaryotic and reproduce asexually (binary fission).

Assessment QuestionsWhat is the major difference between
Eubacteria and Archaebacteria?What are the 3 major phyla of the Eubacteria
kingdom?What are the 3 possible shapes of eubacteria?What is the shape of the eubacteria
