CLASSIFICATION AND
TAXONOMY
JEOPARDY
Ms. Dale’s 7th Grade Science
What is the term we use
to describe a living thing?
ORGANISM!
What are the 5
characteristics of life?
1. Cell(s)
2. Metabolism
3. Response
4. Growth and Development
5. Reproduce
What are organism that
only have one cell called?
Unicellular
What are the 3 things that an
organism needs to live?
1. Water
2. Food
3. Living Space
What is a once living thing?
Once living things were once alive and had
all five characteristics of life at one time,
but no longer carry out the processes of life
What is an obser vation?
An observation is any information
that is gathered with the senses.
What is taxonomy?
Taxonomy- is when scientists
classify organisms, including
living, dead, and extinct.
What is one way we use
classification in our everyday
life?
How we categorize food
in stores, our music and
video collection, and our
clothing in our dressers.
Who is the father of
taxonomy?
Carl Linnaeus
What are taxonomy systems
most commonly based on?
They are based on physical
characteristics or external
structures. However, DNA is
becoming more common to use.
What is the tool called that
provides the reader with two
statements (choices) that
describes characteristics
about items or living things.
What is one way we “extend”
or senses of observation?
Microscopes, rulers,
telescopes, thermometers,
etc.
Dichotomous Key!
What does dichotomous key
mean in Greek?
Dichotomous in Greek means
“divided into t wo parts”
Can taxonomy be used to
classify extinct animals?
YES!
Paleontologists have found
new species of dinosaurs in
Utah over the past few years!
What is the system of giving
every species a unique name
that has two parts called?
Binomial nomenclature is the
system of giving every species a
unique name that has t wo
parts.
In binomial nomenclature
there are two words. What
does the first one represent?
What does the second one
represent?
First word= genus
Second word = species
What is our species common
name?
Our species common name is
humans!
How do you correctly write a
name using binomial
nomenclature?
The first letter of the genus is
capitalized. Each word is in
italics OR underlined.
Example: Homo sapien
OR
(genus) (species)
Homo sapien
(genus) (species)
What is a scientific name?
A scientific name is an
organisms name using binomial
nomenclature
(genus and species)
Do all organisms need air to
survive?
NO!
!
There are organisms that do not need
oxygen to live! Bacteria and Archaea are
the most common. HOWEVER, scientists
found the first ever multicellular organism
that does not need oxygen to live in 2010.
What is a eukaryote?
An organism with a cell that
contains a nucleus
Name each of the
domains of life.
Archaea, Bacteria, Eukarya
What does archaea mean?
Ancient
What domains contain
unicellular prokaryotes?
Archaea and Bacteria
What kingdom contains
organisms that do not fit into
one of the three other
kingdoms in that domain and
are
Protists are eukaryotic
organisms that do not fit into
one of the three other
kingdoms in that domain.
What is a prokaryote?
A prokaryote is an animal
without a nucleus
!
(prokaryote means ‘before
the kernel’)
What do these organisms
have in common?
These organisms are all
eukaryotes. They all have a
nucleus in their cell(s).
How are organisms classified
into domains and kingdoms?
Based on their cell type, their
ability to make food, and the
number of cells in their bodies
Name at least t wo ways that
archaea and bacteria are
alike.
Bacteria and archaea both
both are prokaryotes,
unicellular, and can be
autotrophs or heterotrophs
Why aren’t archaea and
bacteria classified in the same
domain?
Bacteria and archaea are in
separate domains because
their chemical makeup
differs significantly
List 3 characteristics that
members of the plant
kingdom share.
All organisms in the plant
kingdom are eukaryotes,
multicellular, autotrophs
List one organisms, other
than mushrooms, that are
members of the fungi
kingdom.
Molds, mildew, and yeast are
all examples of organisms in
the fungi kingdom
Which of the following
organisms does not belong?
Explain. amoeba, mushroom,
E. coli, moss, dolphin
E. coli does not belong because
the other 4 organisms are
eukaryotes (which means
their cells have a nucleus). E.
coli is a prokaryote (its cell
lacks a nucleus)
What is the main difference
bet ween prokaryotes and
eukaryotes?
Prokaryotes do not have a
nucleus and eukaryotes do
have a nuclues.
If an organism is an
autotroph, you know it
cannot be a member of which
2 kingdoms?
If an organism is an
autotroph (produces its own
food) then it cannot be a
member of the fungi kingdom
or the animalia kingdom
h= Which kingdom contains
organisms that are mostly
decomposers?
The fungi kingdom contains
organisms that are mostly
decomposers
Which of the following
organisms does not belong?
Explain. Dandelion, grass,
seaweed, redwood tree
Seaweed doesn’t belong
because it is a protist and the
rest are plants
Your teacher has shown you an
organism that you’ve never seen
before & you have to determine
which kingdom it belongs to. Below is
a list of characteristics you observe.
1) It is unicellular
2) A nucleus is present
3) It can make its own food
1) It is unicellular
2) A nucleus is present
3) It can make its own food
!
A protist!
Your teacher has shown you an
organism that you’ve never seen before &
you have to determine which kingdom it
belongs to. Below is a list of
characteristics you obser ve.
!
1)It is multicellular
2) There are nuclei present
3) It gets nutrients from dead organisms
4) Other members of this kingdom are
unicellular
1) It is multicellular
2) There are nuclei present
3) It gets nutrients from
dead organisms
4) Other members of this
kingdom are unicellular
!
Fungi
Which domain & kingdom do
you belong to?
You belong to the domain
Eukarya and the kingdom
Animalia!
Which kingdom is sometimes
called the “odds and ends”
kingdom?
Protists are sometimes called the odds and ends
kingdom. This is because its members are so
different from one another. A organism gets placed
in this kingdom if it is a eukaryote, but not a
fungus, a plant, or an animal.
What does it mean if an
organism is an autotroph?
An autotroph is an organism
that can make its own food
Which kingdoms have
members who are
autotrophs?
All organisms in the Plantae
kingdom are autotrophs and
some organisms in the
kingdom Protista are
autotrophs
What does it mean if an
organism is a heterotroph?
A heterotroph cannot make
its own food.
Which kingdoms have
members who are
heterotrophs?
All organisms in the kingdom
Animalia and Fungi and some
organisms in the Protista
kingdom are are heterotrophs
