1. Taxonomy of Organisms
6.12 C

2. Taxonomy
The branch of Science that formally names and classifies organisms by their structure, function and relationships.

3. Domains
All forms of life are classified into 3 Domains. This based on their characteristics. It’s the BROADEST level of organization.
They are…. Bacteria, Archaea & Eukarya

4. Kingdom
Biologist have organized all living things into 6 large groups called Kingdoms. They are classified based on their specific characteristics.
6 Kingdoms: Archaea,
Bacteria, Plant,Animal
Fungi, and Protista

6. Domain: Archaea Kingdom: Archaea Bacteria
Domain Archaea only has ONE Kingdom…Archaea bacteria. They come from EXTREME environments. Most die in the presence of oxygen.
All organisms in the Archaea bacteria Kingdom must be:
Unicellular
Prokaryotic
Autotrophic (Chemotrophs)
Heterotrophic
Asexual Reproduction

7. Domain: Bacteria Kingdom: Eubacteria
Domain Bacteria only has ONE Kingdom…Eubacteria. They live in many different environments. Some need oxygen, but others die in the presence of oxygen.
All organisms in the Eubacteria Kingdom must be:
Unicellular
Prokaryotic
Heterotrophic
Asexual Reproduction

8. Domain: Eukarya Kingdoms: Animal, Plant, Fungi, Protista
This Domain contains the most Kingdoms…4 total. All of the Kingdoms contain organisms that are Eukaryotic. Hence the name Eukarya Domain.
The 4 Kingdoms are:
Plant
Animal
Fungi
Protista

9. Domain: Eukarya Kingdom: Plant
All cells have Nucleus and a Cell Wall.
Ex: mosses, ferns, flowering plants, trees, bushes
They are:
Multicellular
Eukaryotic
Autotrophic
Asexual and Sexual Reproduction

10. Domain: Eukarya Kingdom: Animal
This kingdom is the one that you belong to. All organisms in this kingdom can be divided into vertebrates and invertebrates.
Ex: insects, fish, humans, worms, starfish, dogs, cats, pig, dolphin
They are:
Multicellular
Eukaryotic
Heterotrophic
Mostly Sexual Reproduction
Very few Asexual Reproduction

11. Domain: Eukarya Kingdom: Fungi
Some may confuse Fungi with Plants, but they are NOT plants. Fungi are decomposers, but like plants they do have a cell wall.
Ex: Yeast, mold, mushrooms
They are:
Unicellular and Multicellular
Eukaryotic
Heterotrophic
Asexual and Sexual Reproduction

12. Domain: Eukarya Kingdom: Protista
Protista can be complicated. Some Protista in a dark environment are heterotrophic, but in light they are autotrophic.
Ex: Amoeba, Euglena, Algae, Diatom, and Paramecium
They are:
Unicellular and Multicellular
Eukaryotic
Autotrophic and Heterotrophic
Asexual and Sexual Reproduction
