BACTERIA
Friend
Or
Foe?
3 main shapes of bacteria:
Round = coccus
diplococcus
Rod = bacillus
Spiral = spirilla
streptococcus
REPRODUCTION
Binary Fission
splits into 2 new
Conjugation
exchange of genetic
material
CLASSIFICATION
All bacteria used to be classified under
KINGDOM
MONERA
Now they have been divided into two
kingdoms:
ARCHAEBACTERIA
Prokaryotes (NO nucleus)
Cell walls w/out Peptidoglycan
genes/DNA similar to eukaryotes (!)
*live in EXTREME environments
such as. . .
EUBACTERIA
Prokaryotes (no nucleus)
more of these
live everywhere

water molds
Slime molds
•Feed by absorption- -break
down dead organic matter
•May be saprophytes or
parasites
18
•Make a reproductive structure or
fruiting body that produces
spores
•Often found on decaying wood or
leaves
water molds
•Aquatic water molds are parasites on fish forming
furry growths on their gills
•May act as decomposers in water of dead plants &
animals
•May be pathogenic to plants

Algae are a source of food in the aquatic
ecosystem and produce oxygen
