What do archaea and bacteria not have in common?
Archaea and bacterial cells lack organelles or other internal membrane-bound structures. Therefore, unlike eukaryotes, archaea and bacteria do not have a nucleus separating their genetic material from the rest of the cell.
How is bacteria different from archaea and eukarya?
There are three domains of life: Bacteria (also known as Eubacteria), Archaea, and Eukarya. The Bacteria and Archaea are made up entirely of microorganisms; the Eukarya contains plants, animals, and microorganisms such as fungi and protists.
What do bacteria and archaea have in common?
Both bacteria and archaea have cell membranes and they both contain a hydrophobic portion. In the case of bacteria, it is a fatty acid; in the case of archaea, it is a hydrocarbon (phytanyl). Both bacteria and archaea have a cell wall that protects them.
What is found in eukaryotic cells but not bacteria?
The most obvious difference between eukaryotes and bacteria is that there is a membrane-bounded nucleus in eukaryotes and not in bacteria – again, for the most part: there is a bacterium with the wonderful name Gemmata obscuriglobus that is described as having a double membrane enclosing the DNA in a nucleus-like …
What are the similarities and differences between Bacteria and Archaea?
Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.
What do archaea bacteria and Eukarya all have in common?
Both can carry out asexual reproduction. Translation and transcription that occurs in Archaea is similar to that that occurs in Eukaryota (the one in bacteria is unique). DNA replication in Archaea is similar to that in Eukarya.
Which is a primary difference between all prokaryotes and eukaryotic cells?
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
What do eukaryotes and archaea have in common?
One similarity between domain Archaea and domain Bacteria is that they both contain only prokaryotes while domain Eukarya only contains eukaryotes. A cell wall in domain Archaea has peptidoglycan. The organisms that have a cell wall in domain Eukarya , will have a cell wall made up of polysaccharides.
How is DNA replication similar to that of Eukaryota?
Translation and transcription that occurs in Archaea is similar to that that occurs in Eukaryota (the one in bacteria is unique). DNA replication in Archaea is similar to that in Eukarya.
Where is the DNA found in a prokaryotic cell?
Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1). Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1).
What kind of food does an Archaean eat?
Archaea can eat iron, sulfur, carbon dioxide, hydrogen, ammonia, uranium, and all sorts of toxic compounds, and from this consumption they can produce methane, hydrogen sulfide gas, iron, or sulfur. They have the amazing ability to turn inorganic material into organic matter, like turning metal to meat.
