CLASSIFICATION OF
ORGANISMS
THE 6 KINGDOMS
Kingdom Bacteria

Where are bacteria found?
– Members of this kingdom are found in soil,
water, and other living things

Fun Facts
– Bacteria are believed to have been living on
Earth for more than 3.5. billion years
– This kingdom has more individuals in it than all
the other kingdoms combined
– A handful of dirt contains trillions of bacteria
Kingdom Bacteria



All bacteria are single celled organisms
that do not have a nucleus!
What do we call organisms with these
characteristics?
Bacteria have cell walls
Genetic
material
Cell
Membrane
Kingdom Bacteria

Bacteria can be one of three main
shapes.
– Rod-shaped (bacilli)
– Spherical-shaped ( cocci)
– Spiral-shaped (spirilla)
Kingdom Bacteria

Reproduce by Binary Fission
– one bacteria duplicates its genetic
material and then splits into 2 separate
cells
– the new cell is identical to the parent
Kingdom Bacteria

Some bacteria reproduce sexually
through conjugation
– Two parents
– Transfers some of its genetic material
– Offspring are genetically different from
parents
Kingdom Bacteria

Different types of bacteria are classified by
how they get their food
– Autotrophic
– Heterotrophic
– Decomposers
Kingdom Bacteria


Some bacteria move with the help of
flagellum
Most bacteria cannot move on their
own
Kingdom Bacteria

Roles/Uses
– 99% of bacteria are not harmful to humans
– Bacteria help produce foods such as cheese,
apple cider, and sauerkraut
– Bacteria cause food to spoil
– Some are decomposers
– Some can even clean up oil spills and
gasoline leaks
Can Bacteria Help Us?

Bacteria help us
– Digest food
– Make vitamin K
– Prevent harmful bacteria from attaching to
the intestines
– Insulin-making bacteria help control diabetes
Kingdom
Archaebacteria
Kingdom Archaebacteria

Where are archaea found?
– Most organisms in this kingdom are found
in extreme environments, such as hot
springs
– Can be found in ponds and swamps
– Most archaea prefer environments with
little or no oxygen
Kingdom Archaebacteria

All archaea are prokaryotic organisms

They reproduce using binary fission
Kingdom Archaebacteria

There are 3 main types of archaea
– Heat Lovers—live in extremely hot water
like that found in ocean vents and hot
springs
– Salt Lovers--live in environments with
high levels of salt (ex. Dead Sea and
Great Salt Lake)
– Methane Makers—live in swamps and
animal intestines; give off methane gases
