Archaebacteria
Oldest form of life
Not to be confused with the oldest living
things
Singe cell organism (unicellular)
Found in extreme environments
Geysers
Hotsprings
Volcanic ocean vents
live in extremely harsh environments and
may represent the first cells to have evolved
Sewage treatment
plants, thermal vents, etc.

Acidic,

Anaerobic
Archaebacteria
• Unicellular
• No nucleus
Eubacteria
Second oldest form of life
Single cell organism (unicellular)
Most familiar bacteria
Streptococcus
Lactobacillus
Staphylococcus
Eubacteriasome cause human diseasespresent in almost all habitats on earth
Live in the
intestines of animals
UnicellularNo nucleus
Many bacteria are important environmentally and commercially.
Some are autotrophic but most are heterotrophs
Protists
“Odds and Ends” kingdom
All microscopic organisms that are not
plants, not animal, not bacteria, and not
fungi.
Single cell organism (unicellular)
Protozoa, Amoeba
Protista All live in marine or
freshwater
Most are unicellular
Few are multicellular
Some are autotrophic, others are heterotrophic
3 groups Animal-like
Plant-like
Fungus-likePlant like protists (autotrophic,
cellulose cell walls)
Animal like protists (heterotrophic)
Fungus like protists (absorbtive heterotrophs)
Fungi
Most are multi-cellular organism
Mold, mildew, mushrooms
Some are very important to ecosystems or
as food.
Some cause diseases – ringworm, and
athlete’s foot
Fungus Multicellular, except yeast
Decomposers
Digest food outside their body & then absorb it
Found in marine, freshwater and terrestrial environments
Plants
Second largest kingdom
Multi-cellular organisms
Producers (make their own food)
Without plants life as we know it would not
exist.
Plantae All Multicellular
All Autotrophic
use sunlight to make glucose – Photosynthesis
Cell walls made of cellulose
Animalia
Multicellular
Consumers
Consume food &
digest it inside their
bodies
Feeds on plants or
animals
A Quick Note on Viruses Viruses are much smaller than
bacteria.
Viruses are virulent.
They cause diseases like the flu or chicken pox.
Most biologists agree that viruses are not alive.
Viruses do not move, grow, or carry out respiration.
Viruses need living host cells to reproduce.
Archaea and Eubacteria
unicellular
prokaryotes (no nucleus)
no membrane-bound organelles
Eukarya
more complex
most are multicellular, some unicellular
eukaryotes (have nucleus)
membrane-bound organelles
