Binomial Nomenclature
A two-part naming system
Common name: Human
Common name: Dog
Common name: Tiger
Common name:
Elephant
Since the Linnaean system focuses on physical
similarities alone…molecular studies (genetic
sequences) are not considered.
Genetic similarities between two species are more
likely than physical similarities to show
COMMON ANCESTORY

The THREE domains
1. Bacteria
E. coli
Salmonella typhus
Clostridium
botulinum
Single-celled prokaryotes
Neisseria
gonorrhea
One of the largest groups of organisms on Earth
Can be classified by their traits such as:
* Shape
* Their Need for Oxygen
* Whether they cause disease
The THREE domains
2. Archaea
Single-celled prokaryotes, (without a nucleus)
Haloquadratum
walsbyi
Able to live in extreme environments, (due to the chemical make up
of their cell walls
The THREE domains
3. Eukarya
Made up of all organisms with eukaryotic cells
(Eukaryotic: Have a nucleus and membrane-bound organelles)
Can be single-celled, colonial, or multicellular
Includes 4 Kingdoms:

Protista

Plantae

Fungi

Animalia
Animal Kingdom
* Eukaryotic
Plant Kingdom
* Eukaryotic
• made of cellulose
Fungus Kingdom
• Except for YEAST
which is unicellular
* Eukaryotic
• Decomposer
• made of chitin
Protist Kingdom
• some algae are multicellular
(Plant-like)
or
(Animal-like)
* Eukaryotic
