kingdom archaea and eubacteria

Characteristics of domain Archaea

• classified as a plant or animal

• prokaryotes

• no cell nucleus or other membrane bound organelles

• create their own energy through chemosynthesis and cellular respiration

• extremophiles

• thermoacidophiles

• methanogens

Characteristics of domain eubacteria

• prokaryotes

• no nucleus or other membrane bound organelles

• cell wall of carbohydrate-peptidoglycan to resist damage

archaea and eubacteria structures

bacilli-rod shaped

spirilla-spiral

cocci-spherical

parts of the structure

cell membrane, cytoplasm, flagellum

characteristics of prokaryotes

• lack of a nucleus and other membrane bound organelles

• simple structure

• unicellular

extremophiles

Thermoacidophiles: live in extremely hot and acidic environments

Methanogens: oxidize CO2 to create CH4, commercially used in sewage plants to break down sewage

Halophiles: live in salty solutions

archaea and eubacteria nutrition

chemosynthetic autotrophs: gets energy by breaking down energy of inorganic compounds

Photosynthetic autotrophs: uses the sun’s energy to make energy for themselves

Heterotrophs: cannot make their own food, organic molecules for energy

archaea and eubacteria reproduction

Budding, binary fission

eubacteria reproduction

• spore formation, asexual

• conjugation, sexual reproduction

harmful bacteria

diseases, produce toxins, food poisoning

helpful bacteria

decomposers, digestive tract, nitrogen fixing, food production, pesticides
