CLASSIFICATION
Of
LIVING THINGS
WHAT IS
CLASSIFICATION?
SORTING LIVING
THINGS INTO
GROUPS BASED
ON THEIR
SIMILARITIES
WHY?
We classify because:
•Diversity creates a need to
classify, so we…...
•Sort living things into
categories to…...
•understand characteristics
of living things.

Taxonomy - the scientific study
of how things are classified.
ARISTOTLE
• Made the first
system of
classification
Carolus Linnaeus
made today’s
classification system.
Binomial
nomenclature:
2 part name
based on shared
characteristics.
CANIS LUPUS
The first part of the organism’s scientific
name is its genus & it is capitalized.
Genus is a
classification grouping
that contains
similar, closely related
organisms.
CANIS lUPUS
The 2nd part is
the Species and
it is lower case
Recall, species are
organisms that can
mate and produce
offspring

Why would you want to classify
organisms ??
TO MAKE
THINGS
EASIER!
Taxonomic Key
or dichotomous key
A series of paired statements
that describe physical
characteristics of organisms
TWO DOMAINS:
ARCHAE & EUKARYA
Seven Levels of Classification:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
Example of lion classification
animals
backbone
mammal
carniovre
feline
panther
lion
Animalia
Chordato
Mammalia
Carnivora
Felidae
Panthera
Leo

Living things grouped in 6
kingdoms:
Kingdom
Archaebacteria
Kingdom
Eubacteria
Kingdom
Protista
Kingdom Fungi
Kingdom Plantae
Kingdom Animalia
Archaebacteria
Unicellular organisms
that already existed billions
of years before the dinosaurs.
Scientist’s think they were the
earliest form of life.
Archaebacteria
Live in extreme environments
and can survive where no other
organisms can.
•Unicellular
•Prokaryotes
Eubacteria
These bacteria
are constantly on & around us.
•Good (in yogurt) & bad (strep
throat) bacteria
•Unicellular
•Prokaryotes
Obtaining Food
Some bacteria are autotrophic
and make their own food the
same way plants do. Others are
heterotrophic which means they
consume a variety of foods from
milk to meat.
3 shapes of bacteria
Bacillius – rod shaped
Coccus – spherical
Sprillia - spiral
PROTISTS
Have u ever walked on
the beach and seen
tangled piles of seaweed?
Protist kingdom is
called the odds
and ends kingdom
Some r autotrophs, some r
heterotrpohs - most r unicellular but
a few like seaweed r multicellular
FUNGI
Mushrooms,
molds and
mildews
•Multicellular
• heterotrophs
•eukaryotes
Exception: yeast is unicellular
•Most feed on dead & decaying
organisms
PLANTS:
•vascular & non-vascular
•gymnosperms
• angiosperms
ANIMALS
•Multicellular
•Eukaryotes
Dog, flea
cat cow,
monkey,
wasp,
tarantula,
human,
fish, worm,
etc.
THINK ABOUT IT...

A. Eukaryote
B. Prokaryote
Why do scientists classify
organisms?
A. For organization
B. To determine where
new organisms fit in
C. A and B

C. Homozygote
How do autotrophs and
heterotrophs differ?
A. One goes thru mitosis &
the other does not
B. One makes its own food
and the other does not
