Organisms in the domain Eukarya have membrane-bound organelles, a nucleus, and multiple linear chromosomes, while organisms in the domain Archaea lack membrane-bound organelles, have a single circular chromosome, and their cell walls are chemically different. Eukaryotes generally have more complex cellular structures and processes than archaea.
Organisms in the domain Archaea are unicellular prokaryotes without a nucleus, membrane-bound organelles, or introns in their genes. They also have unique cell wall components. Eukaryotes in the domain Eukarya, on the other hand, have a nucleus and membrane-bound organelles, are typically larger and more complex, and can be unicellular or multicellular.
Both organisms in the domain Eukarya and Archaea have complex cells with membrane-bound organelles, a defined nucleus, and genetic material organized into chromosomes. However, they differ in terms of cell wall composition, membrane structure, and metabolic pathways.
The three-domain system classifies all living things into one of three large domains: Archaea, Bacteria, and Eukarya.The Eukarya domain contains all organisms with eukaryotic cells. From the classification system, then, the Eukarya domain would contain all members of kingdoms Protista, Fungi, Plantae, and Animalia.The organisms that our system puts in kingdom Monera would go into either the Archaea domain or the Bacteria domain, depending on certain characteristics.Those prokaryotic organisms that live in very extreme environments such as boiling hot springs or incredibly salty lakes belong in domain Archaea, while those prokaryotic organisms that live in more "normal" environments would belong in domain Bacteria.Most users of the three-domain system have only one kingdom in Archaea and only one kingdom in Bacteria, but they have many kingdoms in Eukarya. Some users of the three-domain system have kingdoms Protista, Fungi, Plantae, and Animalia in the Eukarya domain, but most split domain Eukarya into many, many different kingdoms.Partial source: "Exploring Creation with Biology" by Dr. Jay L.

Domain Archaea is made of the oldest known organisms, most use chemiosynthesis (inorganic elements) to make energy and are found in more hostile environments (extremeophiles) and are build on the cellular level to survive in them and are similar to Domain Prokaryota. Domain Prokaryota organisms have no membrane bound organelles (chloroplasts, mitochondria, nucleus, ect.), their only genetic code is made of RNA and plasmids, they have a cell wall, are single celled, and move by cillia and flagella. Domain Eucaryota are the most complex and diverse of the three domains. They have DNA as their primary genetic code, membrane bound organelles, and are equipped with a wide array of organelles for specific tissue and organ functions, but some function as single celled organisms.
There used to be 2 Domains in the classification system in taxonomy, Eukaryotes and one which included bacteria and Archea, now there are three, archea have been made a separate Domain.EukaryaBacteriaArchaeaThe three domains, identified by Karl Woese, classify all living things into one of three large domains: Archaea (ar kay' uh), Bacteria, and Eukarya (yoo' kair ee' uh).This was done based on Genetic relationships between the organisms concerned rather than that of Morphological similarities that the system was based upon in the past.Scientists altered the classification of the domains when they were better able to define the genetic structures of living things. A new rDNA comparison analysis led to the development of the three domain system of classification.It is to be noted that the new sector Archea are Prokaryote not Eukaryote, both Archea and Bacteria were joined before under the name Prokaryote, but now they have been separated.The Eukarya domain contains all organisms with eukaryotic cells. From our classification system, then, the Eukarya domain would contain all members of kingdoms Protista, Fungi, Plantae, and Animalia.The organisms that our system puts in kingdom Monera would go into either the Archaea domain or the Bacteria domain, depending on certain characteristics.Those prokaryotic organisms that live in very extreme environments such as boiling hot springs or incredibly salty lakes belong in domain Archaea, while those prokaryotic organisms that live in more "normal" environments would belong in domain Bacteria.

Organisms in the domain Eukarya have membrane-bound organelles, a true nucleus, and typically larger cell sizes compared to organisms in the domain Archaea. Additionally, Eukarya includes plants, animals, fungi, and protists, while Archaea mostly consists of single-celled microorganisms that can thrive in extreme environments.
Eukaryotes have a nucleus, Archaea do not.
