How are the domains bacteria and archaea different from eukarya?

Answer and Explanation:

Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.

The archaea domain is composed of prokaryotic unicellular microorganisms that lack a nucleus, nuclear membrane, and organelles, but they have a cell wall that protects the cell. These organisms are capable of inhabiting in places with extreme temperature, salinity, acidity, or pH, among others. They reproduce asexually. The bacteria domain is composed of a wide group of unicellular prokaryotic microorganisms with a simple structure and sized between 1 to 10 micrometers. These organisms lack a nucleus, nuclear membrane, and organelles. They only present plasmids and ribosomes. They have a cell membrane and a cell wall that protects the cell. Some of them can also present a capsule. They reproduce asexually.The eukarya domain is composed of all the unicellular or pluricellular organisms that have eukaryotic cells that characterize by having a well-defined nucleus surrounded by a complex biological membrane. They also present organelles delimitated by membranes. These organisms reproduce asexually and sexually.

The eukarya domain is divided into four kingdoms: Protist, Fungi, Plantae, and Animalia.

Where are they though?
