Archaebacteria
Ancient bacteria
Eubacteria

True bacteria, such as E. coli

Unicellular

Prokaryotic

Protista
Small eukaryotic organisms
Fungi
Organisms that are not able to undergo photosynthesis and are not plants
Plants

Living things that can undergo photosynthesis

Eukaryotic

Animals
Organisms in this largest kingdom are heterotrophic, multicellular, and eukaryotic in nature
Bacteria that is found in yogurt and in the digestive tract
Eubacteria
Characteristics of protists

Eukaryotic cells

Primarily aquatic

Primarily unicellular

Difference between fungi and plants
Fungi get energy through nutrient absorption, and plants create energy through photosynthesis
Invertebrates
Organisms without a backbone, such as a worm, octopus, and oyster
Vertebrates
Animals that have a backbone, such as a salamander
Characteristics of a primate
Forward-looking eyes, hands and feet that are able to grasp, complex social behaviors and large brains
Classification of humans
Home Sapiens
Homo habilis
First member of the human genus that lived 1.6-2.4 million years ago
Homo erectus
The first known human ancestor that moved out of Africa
Australopithecus
Lived about 2-4 million years ago and was responsible for increasing the diversity of hominins
