Phylogenic Tree
3 Domains:
Eukaryota: fungi,
plants, animals &
protists (multicellular
organisms)
Archaeabacteria:
ancient bacteria
Eubacteria: true
bacteria (singlecelled organisms)
Classification of ALL
Living Organisms
ALL living things can be grouped into 3
domains: Archaea, Bacteria, Eukaryota
1. Domain Archaea (Archaebacteria) –
Prokaryotic, single-celled organisms that
live in extreme environments that
resemble the environments of the ancient
world Ex: Volcanic and oceanic vents
(without oxygen)

Archaebacteria
Methanogenes -live in
swamps, marshes, the
stomachs of animals
and sewage treatment
ponds
Halophiles –live in areas
high in salt content such
as the Dead Sea and
Great Salt Lake
Thermophiles –live in hot
springs with
temperatures ranging
from 60-80° Celsius
Bacteria (Eubacteria)
Largest portion of Monera.
Prokaryotic, single-celled
 Photosynthetic Blue-Green algae (cyanobacteria)
 and Heterotrophic Bacteria...
i) Parasites: Those that take food from living
organism. Mainly disease-causing bacteria.
Ex: E. Coli
ii) Saprophytes: Those that obtain food from
dead and decomposing organic matter.
Ex: Spirochetes
Eukaryotes
Contain a true nucleus.
Ex. fungi, plants,
animals & protists

THE END OF THE UNIT
Most bacteria display one of the
following basic shapes:
1.
2.
3.
Spherical (cocci; singular: coccus)
Rod-shaped (bacilli; singular: bacillus)
Spiral (spirilla; singular: spirillum)
Note: Cocci and bacilli. And sometimes spirilla, form pairs,
clusters, colonies, or chains (filaments) of cells.
Ex: Strept throat is caused by Streptococci a group of cocci
that form chains.
E. Coli
Kingdom Monera
Characteristics of Bacterial Cells:
1. Bacterial cells are prokaryotic. All bacteria are
basically single celled.
2. The cytoplasm of bacterial cells contains no
membrane-bound organelles.
3. Bacterial cells have a single chromosome.
4. Most bacteria reproduce by binary fission.
Bacteria show great metabolic diversity.
Respiration
3 forms:
1.
Obligate aerobic- organisms must have
oxygen to survive (Obligate = needs, Aerobic =
need OXYGEN) (majority of Archaebacteria)
2. Obligate anaerobes- organisms that only
grow in absence of oxygen (Obligate = needs,
Anaerobics = no oxygen)
3. Facultative anaerobes- organisms that
can survive with or without oxygen (majority of
bacteria)
