Archaea
Oldest form of life
Singe cell organism (unicellular)
Have no nucleus or membrane bound organelles
Are more closely related to Eukaryotes despite their
Bacteria like appearance
 3 common types:
• -Thermophiles, live in the hot springs or in deep sea vents
• -Halophiles, live in salty environments like the Dead Sea or
in salt lakes
• -Methanogens, live in methane rich environments like
swamps or stomachs, are anerobic and produce methane
Examples of
Extremophile
Environments
Bacteria
Second oldest form of life
Prokaryotic, single cell organism (unicellular)
Contains no membrane bound nucleus or
organelles like mitochondria
Have single chromosome
Reproduce asexually by binary fission (splitting in
two)
Familiar examples of bacteria
• Streptococcus
• Staphylococcus

Difference Between Bacteria and Archaea
(Prokaryotes)
Archaea
Cell membrane contains
ether linkages
Cell wall lacks peptidoglycan
Bacteria
Cell membrane contains
ester bonds
Cell wall made of
peptidoglycan
Genes and enzymes behave Have only one RNA
more like Eukaryote
polymerase
Have three RNA polymerases React to antibiotics in a
like eukaryotes
different way than Archaea
do
Extremophiles
Protista
“Odds and Ends” kingdom
 A diverse taxonomic group and especially a kingdom (Protista) of
eukaryotic organisms that are unicellular and sometimes colonial or
less often multicellular and that typically include the protozoans,
most algae, and often some fungi (as slime molds).

Fungi
Types of Cells: Unicellular and Multicellular
Fungus is eukaryotic and has cell walls. •
Decomposer, feed on dead or decaying tissue. Fungi digest food by
releasing enzymes to break down organic matter into a form the

fungus can absorb.

Type of Reproduction: – Asexually reproduces with SPORES.

Plantae
Multi-cellular organisms
Most plant organisms contain chlorophyll.
Cell walls of plant cells are comprised of cellulose.
Plants have both organs and organ systems.
They obtain their energy from sun through photosynthesis.
Plants reproduce both by sexual and asexual.
Plants develop a self defense mechanisms.
Organisms within Kingdom Plantae are multicellular,
eukaryotic and autotrophic.
 Lack of motility.
If you don’t know what a common plant looks like your in
trouble…..
Animalia
All animals are multicellular, eukaryotic heterotrophs —they
have multiple cells with mitochondria and they rely on other
organisms for their nourishment.
Adult animals develop from embryos: small masses of
unspecialized cells
Simple animals can regenerate or grow back missing parts
Most animals ingest their food and then digest it in some
kind of internal cavity.
If you don’t know what a common animal looks
like, your in even bigger trouble….
