Organisms classified as Eukarya, such as plants, animals, and fungi, have complex cells with a defined nucleus and membrane-bound organelles, allowing for compartmentalization of cellular processes. In contrast, Archaea and Bacteria are prokaryotic organisms, which lack a nucleus and membrane-bound organelles, and typically have simpler cell structures. Additionally, Eukarya and Archaea have more similar genetic and biochemical processes than Eukarya and Bacteria, despite Archaea and Bacteria both being unicellular. These fundamental differences in cellular organization and genetic makeup define the three domains of life.

Is bacillus archaea bacteria or eukarya?

Bacillus is a genus of bacteria, specifically classified within the domain Bacteria. It is not archaea or eukarya; rather, it belongs to the prokaryotic group of organisms. Bacteria are distinct from archaea and eukarya in their cellular structure and genetic makeup. Therefore, Bacillus is purely a bacterial organism.


What the broadest group into which an organism can be classified?

The broadest group into which an organism can be classified is a domain. There are three domains: Bacteria, Archaea, and Eukarya. Organisms are grouped into these domains based on their cellular structure and genetic makeup.


What domain does a single celled organism belong in?

A single-celled organism belongs to the domain of Bacteria, Archaea, or Eukarya. These domains encompass all forms of life on Earth, with single-celled organisms falling into the categories of bacteria, archaea, or protists within the Eukarya domain.


What are the domains of living organisms?

Living organisms can be classified into three domains: Bacteria, Archaea, and Eukarya. Bacteria and Archaea are prokaryotic domains, while Eukarya includes all organisms with eukaryotic cells, such as plants, animals, fungi, and protists.


What three characteristics determine the domain or kingdom an organism belongs to?

bacteria, archaea, and eukarya


Plants are classified in the domain .?

Plants are classified in the domain Eukarya.


Are archaebacteria and eubacteria both protists?

No, archaebacteria and eubacteria are not considered protists. They are both types of bacteria that are classified in different domains (Archaea and Bacteria), separate from the domain Eukarya where protists are found.


What kingdom would an organism that is prokaryotic unicellular and has a cell wall belong to?

The organism would belong to the kingdom Bacteria.


What could be used to distinguish between an organism in the domain bacteria and one in the domain eukarya?

One way to distinguish between an organism in the domain Bacteria and one in the domain Eukarya is by looking at their cell structure. Bacteria have prokaryotic cells without a nucleus or membrane-bound organelles, while Eukarya have eukaryotic cells with a nucleus and membrane-bound organelles. Additionally, the presence of peptidoglycan in the cell wall is a characteristic feature of bacteria, which is absent in eukaryotic organisms.


How are organisms classified into domain and kingdom?

Organisms are classified into domains based on their cellular structure and composition. The three main domains are Bacteria, Archaea, and Eukarya. Within the Eukarya domain, organisms are further classified into kingdoms based on shared characteristics such as cell type, nutrition, and reproduction methods.


What are the 3 biological domains?

Archaea, Bacteria, and Eukarya. Archaea are some of the oldest single celled organisms on the planet due to their capability to survive in extreme conditions. Bacteria, also called eubacteria or true bacteria, are composed of prokaryotic cells, but their cell walls have different structures, components in them. Eukarya are composed of eukaryotic cells and contain most the multicellular organisms in our world such as animals, plants, protists, and fungi. Hope this helps.


Name for a single celled organisim?

Life consists of three domains; Archaea, Bacteria and Eukarya. Of these domains, Archaea and Bacteria consist exclusively of single celled organisms. Additionally, one of the four kingdoms of Eukarya, i.e. Protista, consists of single celled organisms.So single celled organisms could be referred to as Archaea, Bacteria and Protista.
