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.
