Characteristics of Bacteria
• Domains: Archae &
Bacteria
• Kingdoms: Archaebacteria
& Eubacteria
• Prokaryotic Cells: cells
without a defined nucleus
and cell organelles
• Unicellular Organisms
• Microorganisms
Cyanobacteria

• Monera formerly housed all bacteria, but now bacteria are
divided into two kingdoms: Archaebacteria and Eubacteria
Archae: harsh, hostile
environment
Habitat
Eubacteria: everywhere
Differences
Archae: no peptidoglycan
Cell Walls
DNA
Eubacteria: has
peptidoglycan
Archaebacteria is more like
the genetic sequence of
eukaryotes

• 3 Hostile Environments
of Archaebacteria
• 1) Oxygen Free:
Marshes, Digestive
Tracts, Sewage
• 2) High Salt Content:
Dead Sea, Great Salt
Lakes
• 3) Hot Acidic Waters:
Sulfur Springs, Ocean
Vents

From other organisms: parasites/saprophytes
Gets nutrients from dead or decaying organisms

• Gram Staining
• Helps identify the type
of bacteria by the
presence of
peptidoglycan in the
cell walls

Reproduction
Asexual Reproduction:
Binary Fission
Sexual Reproductive:
Conjugation ….chromosomes
are transferred through the
pilus

Bacteria “Mix-Up”
Group 1
Map out a possible
sequence of events
predicting the spread of
pneumococcus, a
bacterium that causes
pneumonia, in a crowded
nursing home. Most of
the residents in the
nursing home are elderly
and their immune systems
are impaired. Consider all
the people that pass by
each day and who these
people interact with
outside their homes.
Group 2
Create a 3D model of the
three shapes of bacteria
AND the three bacterial
growth patterns.
Group 3
Calculate the rate a
bacterium cell replicates
AND create a poster
informing the public how
to avoid and prevent the
spread of bacterial
infections.
