Answer:
-8 taxonomic levels: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
- 6 kingdoms: Eubacteria, Archaebacteria, Protist, Fungi, Plantae, Animalia.
Step-by-step explanation:
Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.
The categories where organisms are classified into are:
- 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.
- Kingdom: Includes different phyla closely relates. The bacteria domain includes the Eubacteria kingdom. The archaea domain includes the archaebacteria kingdom. Finally, the eukarya domain is divided into four kingdoms: Protist, Fungi, Plantae, and Animalia.
- Phylum: Includes different classes closely related.
- Class: Includes different orders closely relates.
- Order: Includes different families closely related
- Family: Includes different genera closely relates
- Genus: Includes many species.
- Species
