What is the difference between bacteria and archaea?
Responses will vary. A possible answer is: Bacteria contain peptidoglycan in the cell wall; archaea do not. The cell membrane in bacteria is a lipid bilayer; in archaea, it can be a lipid bilayer or a monolayer. Bacteria contain fatty acids on the cell membrane, whereas archaea contain phytanyl.
Can archaea cause disease in humans?
No definitive virulence genes or factors have been described in archaea to date. Nevertheless, archaea may have the means, and they certainly have the opportunity, to cause disease. Archaea share some characteristics with known pathogens that may reflect the potential to cause disease.
What do archaea bacteria and eukarya have in common?
These groups are the Bacteria, the Archaea, and the Eukarya. These organisms are eukaryotes, meaning they have membrane-enclosed nuclei within their cells. The Bacteria and Archaea are both considered prokaryotes, because their cells lack true nuclei, meaning a membrane does not enclose their genetic material.
What are some similarities and differences between bacteria archaea and eukaryotes?
Bacteria and Archaea differ in how they gain energy. Bacteria gain energy either by being phototrophs, lithotrophs or organotrophs. One similarity between domain Archaea and domain Bacteria is that they both contain only prokaryotes while domain Eukarya only contains eukaryotes.
What is the difference between eukarya archaea and bacteria?
Bacteria: cells do not contain a nucleus. Archaea: cells do not contain a nucleus; they have a different cell wall from bacteria. Eukarya: cells do contain a nucleus.
What makes bacteria archaea eukarya very significant?
The Archaeans possess unique, ancient evolutionary history for which they are considered some of the oldest species of organisms on Earth, most notably their diverse, exotic metabolisms, which allow them to feed on inorganic matter.
What are the similarities between bacteria and archaea?
Similarities. Both the types have the almost same size which varies from 0.5 – 4 micron and so are said to be smallest cell in existence. They both lack membrane-bounded organelles and nucleus. Archaea and bacteria lack multicellularity, and the chromosome is single and circular.
What are the seven animal kingdoms?
The Animal Kingdom contains these seven Phyla: Porifera, Cnidaria, Platyhelminthes, Annelida, Mollusca, Arthropoda, and Chordata.
