Six Kingdoms of Life

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.

extreme environments

HOT,

Acidic,

Salty,

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

Animals

Largest kingdom

Multicellular

Consumers – must eat for energy

Over 1 million known species

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
