13. Kingdom Eubacteria
 Bacteria can live in many places on earth, inhabiting a
wide variety of habitats, including other organisms
 Unicellular
 Prokaryotic
 Autotrophic or heterotrophic
 Thick cells walls with peptidoglycan

14. Kingdom Eubacteria
 Bacteria come in
different shapes, such
as round, spiral and
rod-shaped.

15. Kingdom Eubacteria
 Bacteria can cause a wide variety of diseases,
such as strep throat, food poisoning and the
Black Death (bubonic plague of the Middle Ages)

16. Kingdom Eubacteria
 Bacteria also play an
important role in
decomposition,
nitrogen fixation and
human digestion (E.
coli)
Soybean root containing
billions of bacteria

17. Kingdom Eubacteria
 Procholorococcus –
an autotrophic
bacterium – What
does that mean about
how it gets its
nutrients?

18. Kingdom Eubacteria
 Bacteria from an
Nitrifying Trickle Filter
(NTF) stained with
acridene orange. The
stain makes
DNA appear yellow
and
RNA appear orange.

19. Kingdom Archaebacteria
 Bacteria that live in extreme habitats, such as hot
springs, geysers, volcanic hot pools, brine pools, black
smokers
 Unicellular
 Prokaryotic
 Autotrophic or heterotrophic
 Cell walls without peptidoglycan

20. Kingdom Archaebacteria
Morning Glory Pool in Yellowstone National Park – note the bright colors
from the archaebacteria growing in the extremely hot water.

21. Kingdom Archaebacteria
 Some like it hot! Bacillus infernus

22. Kingdom Archaebacteria
 Archaebacteria can
live deep in the ocean
near geothermal
vents called black
smokers
 There is no light, so
they carry out
chemosynthesis
instead of
photosynthesis

23. Kingdom Protista
 Extremely diverse group
 Eukaryotic
 Most unicellular, some colonial, some multicellular
 Autotrophic and heterotrophic
 Some with cell walls containing cellulose; some carry
out photosynthesis with chloroplasts

24. Kingdom Protista
Volvox – a colonial protist
Euglena - autotrophic
A slime mold
Amoeba - heterotrophic

25. Kingdom Fungi
 Eukaryotic
 Most are multicellular
 Heterotrophic (decomposers)

32. Linnaeus developed the scientific
naming system still used today.
 Taxonomy is the science of naming and classifying organisms.
• A taxon is a group of organisms in a classification system.
White oak:
Quercus alba

33.  Binomial nomenclature is a system of giving two names for organisms.
– uses Latin words
– scientific names always written in italics
– two parts are the genus name and species descriptor

34. • A genus includes one or more physically similar species.
– Species in the same genus are thought to be closely
related.
– Genus name is always capitalized.
• A species descriptor is the second part of a scientific name.
– always lowercase
– always follows genus
name; never written alone
Tyto alba

35. Linnaeus’ classification system has
seven levels.
 Each level is
included in the level
above it.
• Levels get
increasingly
specific from
kingdom to
species.

53.  What is the hierarchical system of classifying living
things?
 The hierarchical system of classifying living things is
called taxonomy. It is a system of grouping organisms
based on their characteristics.
 What are the three domains of life?
 The three domains of life are Bacteria, Archaea, and
Eukarya.
 What are the six kingdoms of life?
 The six kingdoms of life are Bacteria, Archaea,
Protista, Fungi, Plantae, and Animalia.

54.  What are the characteristics of prokaryotes?
 Prokaryotes are organisms that do not have a nucleus
or other membrane-bound organelles.
 What are the characteristics of eukaryotes?
 Eukaryotes are organisms that have a nucleus and
other membrane-bound organelles.
 What are the characteristics of animals?
 Animals are multicellular, heterotrophic organisms that
can move.
 What are the characteristics of plants?
 Plants are multicellular, photosynthetic organisms that
cannot move.
 What are the characteristics of fungi?
 Fungi are eukaryotic organisms that are neither plants
nor animals. They are heterotrophic and absorb
nutrients from their environment.

55.  What are the characteristics of protists?
 Protists are a diverse group of eukaryotic organisms that
do not fit into any of the other three domains. They can
be unicellular or multicellular.
 What are the characteristics of archaea?
 Archaea are prokaryotic organisms that are found in
