Bacteria are
prokaryotic. What
does this mean?
Prokaryotic means that a
cell does not have a
nucleus or any other
membrane bound
organelles.
Back to Game Board
Bacteria have been
divided into two
domains. Name the two
domains of bacteria.
Domain Archaea
Domain Bacteria
Back to Game Board
To what kingdom do the
“true” or common
bacteria belong?
Kingdom Eubacteria
Back to Game Board
The ancient forms of
bacteria that can survive in
very hostile environments
belong to what kingdom?
Kingdom Archaebacteria
Back to Game Board
One of the ways that the bacteria
are separated into two different
domains is based on the chemical
composition of their cell walls.
Are the cell walls of Archaea
similar or different from
Eubacteria?
different
Back to Game Board
Identify the structure
below. What is its
function?
1) The structure is flagella.
2) Its function is to help the
bacteria move.
Back to Game Board
These pictures represent the three
different shapes of bacteria. Even though
the shapes are different, name 2 ways
they are all similar.
coccus
(sphere
shape)
bacilli
(rod
shape)
Spirillium
(spiral
shape)
1) They are single –celled.
2) They are prokaryotes(lack nucleus).
3) They are in the Bacteria Kingdom.
Back to Game Board
You have been asked to investigate a new species.
It has :
1) It has only 1 cell
2) no nucleus
3) is found on areas where eubacteria are found.
4) It grows when placed in sunlight.
What cell type is it ? _____________________
What cell number is it ?___________________
Is it able to make its own food? _____________
What is that called?_______________________
prokarote
unicellular
sunlight
autotoph
Back to Game Board
Look at the picture below.
What type of bacterial
reproduction is it? Both
names, please.
Asexual or binary
fission
Back to Game Board
List two reasons why
bacteria are
important to humans.
They are important as decomposers
(breakdown of dead organisms.
They are used to make a variety of foods
(yogurt, sour cream, cheese, etc.)
Located in stomach to help animals digest
their food.
Back to Game Board
An new organism was found in
the Amazon jungle- it is
multicellular. To what domain
does it probably belong ?
Eukaryote, because all
multicellular organisms
have a nucleus.
Back to Game Board
Bacteria reproduce most
often by binary fission.
Describe this process.
During binary fission a
single cell divides to form
two identical cells. It is
asexual reproduction.
Back to Game Board
Look at the photo below. What type of
organism is most likely to live there?
Why?
Archaea, because they are most
likely to live in extreme
environments.
Back to Game Board
In order to be considered part of a
species you must have 3 things.
What are they?
1.Must have similar characteristics.
2.Must be able to produce fertile
offspring.
3. Must have similar DNA.
Back to Game Board
The scientific study of how living
things are classified is called
____________.
Taxonomy.
Back to Game Board
Both Archaea and Eubacteria
have similar characteristics.
Name 2 of them.
1) They are prokaryotes
2) They are unicellular
3) They may be autotrophs or
heterotrophs.
4) They have been on Earth
for billions of years.
Back to Game Board
What name is given to the
short sticky structures that
help attach a bacterium to a
food source or to another
bacterium?
pilus
Back to Game Board
Is the DNA of Bacteria
contained in a nucleus?
No, that is why they are
called prokaryotes
(before nucleus).
It is a single, circular
strand of DNA.
Back to Game Board
Which is not one of the 4
kingdoms of eukaryotes?
1)
2)
3)
4)
fungi
protists
archaea
plants
3) archaea. They are
prokaryotes.
Back to Game Board
The process of change that occurs
in an organism’s life to produce a
more complex organism is called:
1)
2)
3)
4)
Response
Development
Evolution
growth
4) growth
Back to Game Board
What name is given to an
organism that lives on dead,
decaying matter?
decomposer
Back to Game Board
You are investigating a new
species found on the forest
floor. It is a heterotroph,
unicellular, and has a nucleus.
To what kingdom does it
probably belong?
Fungi
Back to Game Board
What name is given to an
organism that uses sunlight as
a source of energy to build
molecules of glucose?
Autotroph
Back to Game Board
The 2 kingdoms that contain
only heterotrophs are animals
and:
1) Archaea
2) Fungi
3) Protists
4) bacteria
2) Fungi
Back to Game Board
Are some bacteria
autotrophs and some
heterotrophs?
Yes, some are autotrophs
(plant-like) and some are
heterotrophs (animal-like).
Back to Game Board
True of False?
All bacteria cause diseases.
False
Most bacteria are beneficial
or benign.
Back to Game Board
Bacteria can reproduce at an
amazing rate, doubling their
numbers by cell division
every 20 minutes.
True
Back to Game Board
An organism that is made up
of many cells is unicellular.
True or False?
False.
That would be
multicellular.
Back to Game Board
An organism whose cells contain
a nucleus is a eukaryote.
True or False?
True
Back to Game Board
The 6 characteristics of living
things are:
1) Have cells
2) The ability to move
3) Obtain and use energy
4) Respond to their environment
5) Grow and develop
6) Have chemicals of life
False
2) Movement is not a characteristic
of living things.
* The missing characteristic is
reproduction.
