When first discovered in 1977 archaebacteria were classified as bacteria. They are now called Archaea. This change is to emphasise the difference between archaea and bacteria. Archaea are one of the three domains of life suggested by Carl Woese. The other two are Prokaryotae (bacteria) and Eukaryotae (everything else - plants, animals, fungi and protoctists). The features which distinguish archaea from other organisms include: 1) They have prokaryote cells (which have significant differences from other prokaryotes ie the bacteria) 2) The have lipids in their cell membranes composed of branched hydrocarbon chains attached to glycerol by ether linkages, instead of ester linkages 3) Their cell walls do not contain peptidoglycan, as bacterial cell walls do 4) They differ from bacteria in their sensitivity to antibiotics 5) They contain ribosomal RNA (rRNA) which differes from that found in bacteria and eukaryotes.

What is the order for archaebacteria?
Archaebacteria are classified into four main phyla: Euryarchaeota, Crenarchaeota, Thaumarchaeota, and Korarchaeota. These phyla are further divided into various classes, orders, families, and genera based on their genetic and physiological characteristics.
What is the order of kingdom archaebacteria?
The kingdom Archaebacteria is divided into several phyla, including Euryarchaeota, Crenarchaeota, and Thaumarchaeota. These phyla are further divided into classes, orders, families, and genera based on genetic and biochemical characteristics. The specific order of the kingdom Archaebacteria depends on the classification system being used.
What are characteristics of archaebacteria?
Archaebacteria are unicellular prokaryotes that are the oldest living organisms on Earth. Some characteristics include survival in oxygen-free environments, being extremophiles and reproduction is asexual.
Is mitochondria Archaebacteria or Eubacteria?
Mitochondria are not classified as either Archaebacteria or Eubacteria. They are actually believed to have originated from an ancestral endosymbiotic event involving an alphaproteobacteria, which is a type of Eubacteria. Mitochondria themselves have their own unique characteristics and are considered organelles within eukaryotic cells.
What are the characteristics of each?
1 Archaebacteria- prokaryotes, Ancient Bacteria, have hard cell wall, live in harsh environments 2 Eubacteria-Prokaryotes, Don't live in harsh places, similar to archaebacteria 3Protista- eukaryote, unicellular ,slime molds, algae, amoeba 4Fungi- heterotrophs, multicellular, mushrooms, mold 5plants 6 Animals
What reason is there for giving Archaebacteria and Eubacteria their own domains?
After the discovery of archaebacteria, it was decided that archaebacteria and eubacteria have too many different characteristics that they need their own domains.
Is streptococcus archaebacteria or eubacteria?
Streptococcus is a eubacteria, not an archaebacteria. Eubacteria are the more common and diverse group of bacteria, while archaebacteria are a distinct group with unique characteristics. Streptococcus bacteria are commonly found in the human body and can cause various illnesses like strep throat.
What is the order for archaebacteria?
Archaebacteria are classified into four main phyla: Euryarchaeota, Crenarchaeota, Thaumarchaeota, and Korarchaeota. These phyla are further divided into various classes, orders, families, and genera based on their genetic and physiological characteristics.
What are some characteristics of archaebacteria?
Archaebacteria are the oldest organisms living on earth. They are unicellular prokaryotes and belong to the kingdom Archaea. They can be found in very harsh conditions such as volcanic vents or the tundra.
What is the order of kingdom archaebacteria?
The kingdom Archaebacteria is divided into several phyla, including Euryarchaeota, Crenarchaeota, and Thaumarchaeota. These phyla are further divided into classes, orders, families, and genera based on genetic and biochemical characteristics. The specific order of the kingdom Archaebacteria depends on the classification system being used.
What are characteristics of archaebacteria?
Archaebacteria are unicellular prokaryotes that are the oldest living organisms on Earth. Some characteristics include survival in oxygen-free environments, being extremophiles and reproduction is asexual.
What type of cell is Archaebacteria?
Archaebacteria, now known as Archaea, are a type of single-celled microorganism that can thrive in extreme environments. They have unique molecular characteristics that differentiate them from both bacteria and eukaryotes.
What does the separation of the archaebacteria into a separate domain indicate about their evolutionary history and relationship to other organisms?
The separation of archaebacteria into a separate domain suggests that they have a distinct evolutionary history and are not closely related to other organisms in the traditional bacteria domain. This indicates that archaebacteria have unique characteristics and may have diverged early in the evolutionary timeline.
How do scientists classify archaebacteria?
Scientists classify archaebacteria based on their genetic and biochemical differences from other bacteria. They use molecular techniques like DNA sequencing to compare the genetic makeup of archaebacteria with that of other organisms to determine their evolutionary relationships. Additionally, scientists study the unique features of archaebacteria's cell walls, membranes, and metabolic processes to classify them into different groups.
What is the common name for the Archaebacteria kingdom?
The common name for the Archaebacteria kingdom is archaea.
What are characteristics of the kingdom archaebacteria?
The archaebacteria is a unicellular organism without a nucleus. They are known to survive in extreme climates and environments. The first were discovered in 1977 in the boiling hot springs at Yellowstone National Park.
What are three distinguishing characteristics of archaebacteria?
Archaebacteria have unique cell walls that lack peptidoglycan, a common component in bacterial cell walls. They are able to thrive in extreme environments such as hot springs, deep sea vents, and highly acidic or alkaline conditions. Archaebacteria have a different genetic makeup compared to bacteria and eukaryotes, with certain genes and metabolic pathways resembling those of eukaryotic cells.
