['a. Bacteria are prokaryotic cells.', 'b. Like the Eukarya, they have membranes composed of unbranched fatty acid chains attached to glycerol by ester linkages (see Fig. ... ', 'c. The cell walls of Bacteria, unlike the Archaea and the Eukarya, contain peptidoglycan.', 'e.']

One similarity between domain Archaea and domain Bacteria is that they both contain only prokaryotes while domain Eukarya only contains eukaryotes. ... A difference between all three domains is what their cell walls contain. A cell wall in domain Archaea has peptidoglycan.

Archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and ...

Summary. There are three basic shapes of bacteria: coccus, bacillus, and spiral.

What are the three domains of life? Bacteria, Archaea and Eukarya are the three domains of life.
1359381
Evolution of Prokaryotes The domain Bacteria comprises all organisms in the kingdom Bacteria, the domain Archaea comprises the rest of the prokaryotes, and the domain Eukarya comprises all eukaryotes, including organisms in the kingdoms Animalia, Plantae, Fungi, and Protista.

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. 3. The three domains are the Archaea, the Bacteria, and the Eukarya. 4.

Bacteria have a unique compound called peptidoglycan in cell walls. Archaea have unique phospholipids in their plasma membrane and hydrocarbon tails that contain isoprene.

The domains Bacteria and Archaea are the ones containing prokaryotic organisms. The Archaea are prokaryotes that inhabit extreme environments, such as inside of volcanoes, while Bacteria are more common organisms, such as E. coli.

Bacteria, Archaea and Eukarya are the three domains of life. These domains are based on: The cellular composition of organisms. Archaea are the smallest and simplest types of cells, those without a nucleus.
303952
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.

 The phylums under domain bacteria include Proteobacteria, Chlamydias, Spirochetes, Cyanobacteria, and Gram- positive bacteria. 2. Korarchaeum cryptofilum These archaea have only been found in high temperature hydrothermal environments, particularly hot springs.

Three domains. Life on earth is classified into three domains: Bacteria, Archaea and Eukarya. The first two consist completely of single-celled microbes. None of them have a nucleus.
462943
The new domain names are Bacteria, Archaea and Eukarya, where Eukarya consists of organisms whose cells have a nucleus. ... Unique archaea characteristics include their ability to live in extremely hot or chemically aggressive environments, and they can be found across the Earth, wherever bacteria survive.

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.
576157
Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
371574
The three domains include: Archaea - oldest known domain, ancient forms of bacteria. Bacteria - all other bacteria that are not included in the Archaea domain. Eukarya - all the organisms that are eukaryotic or contain membrane-bound organelles and nuclei.
