Taxonomy Overview

Taxonomy is the science of naming and classifying organisms based on structural comparisons and genetic evidence.
There are 8 levels of taxonomy, starting from Domain down to Species.

Taxonomic Categories

Domain is the largest taxonomic category, including Archaea, Bacteria, and Eukarya.
The six kingdoms of life include: Eubacteria, Archaebacteria, Protista, Fungi, Plantae, and Animalia.

Kingdom Animalia

Composed of multicellular, eukaryotic organisms that are heterotrophic and lack a cell wall.
Includes a diverse range of species from insects to elephants, classified into vertebrates and invertebrates.

Kingdom Plantae

Multicellular and eukaryotic, Plantae are autotrophic organisms with a cell wall made of cellulose.
Plant species exhibit a vast range in size, from 1 mm to 115 m.

Kingdom Fungi

Includes unicellular or multicellular, eukaryotic organisms that are heterotrophic and have a cell wall made of chitin.
Comprises important decomposers such as mushrooms, yeasts, and molds.

Kingdom Protista

Primarily unicellular and eukaryotic, Protista consists of organisms that do not fit into other eukaryotic kingdoms.
Organisms may or may not possess cell walls and can be either autotrophic or heterotrophic.

Kingdom Archaebacteria

Archaebacteria are unicellular, prokaryotic organisms that possess cell walls.
They can be autotrophic or heterotrophic, with many living in extreme environments.

Kingdom Eubacteria

Eubacteria are unicellular and prokaryotic, characterized by cell walls containing peptidoglycan.
They can be autotrophic or heterotrophic, with some species capable of photosynthesis, while others are disease-causing or decomposers.

Summary of Biological Domains

Bacteria: Eubacteria
Archaea: Archaebacteria
Eukarya: Comprises Animalia, Plantae, Protista, and Fungi.

Kingdom Characteristics

Body type can be unicellular or multicellular.
Organisms may be prokaryotic or eukaryotic based on cell type.
Most kingdoms have distinct cell wall structures.
Nutritional modes include autotrophic or heterotrophic.
