Archaea are single-celled organisms with a simple cell structure. They lack a nucleus and membrane-bound organelles like mitochondria. Their cell walls are often made of unique molecules like pseudopeptidoglycan or S-layer proteins.
Protests are eukaryotic organisms with distinct cellular structures and organelles, while bacteria and archaea are prokaryotic organisms lacking a true nucleus and membrane-bound organelles. Additionally, protests typically have a more complex cellular organization and can exhibit various forms of motility, whereas bacteria and archaea are typically unicellular and exhibit simpler structures.
Archaea and Eubacteria are the most similar in physical characteristics, as both are prokaryotic organisms lacking a nucleus and membrane-bound organelles. They share similar cellular structures, such as the presence of a cell wall and the ability to reproduce asexually. In contrast, viruses are acellular and do not possess the cellular structures found in Archaea or Eubacteria, while Eukarya have more complex cellular characteristics.
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.
Organisms are classified as prokaryotes or eukaryotes primarily based on cellular structure. Prokaryotes, such as bacteria and archaea, lack a defined nucleus and membrane-bound organelles, possessing a simpler cellular organization. In contrast, eukaryotes, which include animals, plants, fungi, and protists, have a well-defined nucleus and various membrane-bound organelles, enabling more complex functions. This distinction reflects differences in genetic material organization, cellular complexity, and evolutionary lineage.
That description is more characteristic of bacteria, as bacteria typically have a simpler cell structure with fewer organelles compared to eukaryotic cells. Archaea, on the other hand, can have structures that resemble organelles and have more complex cellular machinery.
No, archaea do not possess organelles within their cellular structure.

No, prokaryotes are not classified as a kingdom. Prokaryotes are a type of cellular organization found in bacteria and archaea, which are typically classified into two separate domains: Bacteria and Archaea. The traditional Five Kingdom classification system recognizes prokaryotes within the Kingdom Monera, but this system is now considered outdated in modern taxonomy.
A group of microorganisms that resemble bacteria but are different from them such as the composition of their cell walls. Archaea usually live in extreme, often very hot or salty environments. The archaea are considered a separate kingdom in some classifications. Some scientists believe that archaea were the earliest forms of cellular life.
The three broad groups of life are typically classified into domains: Archaea, Bacteria, and Eukarya. Archaea and Bacteria consist of prokaryotic organisms, which lack a nucleus, while Eukarya includes all eukaryotic organisms, such as plants, animals, fungi, and protists. This classification reflects fundamental differences in cellular organization and genetic makeup among these groups.
The six kingdoms are Animalia (animals), Plantae (plants), Fungi, Protista (protists), Archaea, and Bacteria. Organisms are classified into these kingdoms based on their cellular organization, mode of nutrition, and other characteristics.
Archaea and eukaryotes are similar in that they are both types of cells that have a defined nucleus and other organelles. They also share some similarities in their genetic material and cellular processes.

Cellular Level Organization means that the organism only contains cells... Meaning it has no tissues nor organs....
