Classification
to group ideas, information, or objects based on similarities
Classifying: _______________________________________
_________________________________________________
the science of grouping and naming organisms
Taxonomy: ________________________________________
_________________________________________________
Aristotle: _________________________________________
the first to classify living things into 2 kingdoms: plants and animals
_________________________________________________
came up with a two-word naming system called
Carolus Linnaeus: __________________________________
binomial nomenclature
_________________________________________________
Binomial Nomenclature: a 2-name system where organisms are
Genus
species
called by their __________
and ______________
names.
housecat
Ex: Felis catus is a ___________________.
Kingdom
Phylum
Today’s classification system has 7 groups: ________________,
_________________,
Class
Order
Family
Genus
_______________,
__________________,
__________________,
______________,
species
and __________________.
Organisms are divided into ____
6 Kingdoms: ___________________,
Archaebacteria
_______________,
Eubacteria
Protista
Fungi
Plantae
Animalia

steps with 2 descriptions at each step

first
pair of descriptions!
Latin
Reasons for using Scientific Names (usually based on ________________
or
Greek
________________
words):
communication
errors
1. To avoid ______________________
__________________
due to
common names referring to different organisms.
descriptive __________________
information
2. To give ________________
about the organism.
organize
3. To _________________
and easily find ________________
information
about an organism.
Characteristics of Organisms in the 6 Kingdoms
prokaryotic
I. Archebacteria and Eubacteria – The members of these 2 kingdoms are ________________
membrane-covered
organelles
meaning that they have no __________________________
__________________.
smaller
Cells in these 2 kingdoms are __________________
than cells in the other 4
chromosome
kingdoms. They have a single, circular _____________________
and a __________
cell
wall
cocci
____________.
They come in 3 basic shapes: _______________
(spherical),
__________________
bacilli
(rod-shaped), and ____________________
spirilla
(spiral-shaped). Most
binary
fission
reproduce by _________________
_________________.
Some bacteria survive in
endospores
harsh conditions by becoming _____________________
when they grow a thick,
protective _____________________.
Endospores can survive ________________,
membrane
freezing
boiling
extremely
dry
______________________,
and ________________
_________
environments. Some
bacteria can move through liquids using ______________________.
flagella
II. Eubacteria – These are classified by the way they get _____________.
food
Many are
decomposers
parasites
_______________,
breaking down dead organisms. Others are __________________,
living
obtaining food from other _________________
organisms. Still others are
producers
cyanobacteria
________________________,
called ____________________,
which make their own
photosynthesis
food in the process of ______________________________,
which is
carbon dioxide
water
sunlight
glucose
oxygen
________________
+ _____________
+ ______________
 ___________
+ ________.
III. Archebacteria – These bacteria live in _________________
extreme
_____________________
environments
Yellowstone
National
Park
such as the hot springs in ____________________
_______________
_____________
Antarctica
cell
walls
and in the ice in ______________________.
Their ___________
___________
are
chemically different than those of _______________________,
or they may not have
Eubacteria
methane
makers
heat
them at all. The 3 kinds are ______________
_______________,
___________
_______________,
lovers
and _______________
salt

lovers
IV. Uses for Bacteria
A. Since bacteria break down substances, they can change some of the food we eat.
milk
cheese
Yogurt is made by the bacterial breakdown of _____________,
as is ____________.
Sauerkraut is made from _______________
and a bacterial culture. Vinegar is made
cabbage
grape
juice
from the bacterial decomposition of ___________
______________.
medicines
B. Bacteria are also used to make _________________,
cleansers, and other products.
oil
spills
They are also used to clean up ________
_____________.
C. Nature uses bacteria to clean up ____________
dead
organisms. These bacteria are called
saprophytes
_______________________
because they decompose dead plants and animals and
recycle the nutrients so other organisms can use them. Without bacteria, there would
layers
be ______________
of dead organisms spread all over the Earth.
nitrogen
D. Nitrogen-fixing bacteria change the ______________
in the air into a usable form
for plants and animals.
E. Many bacteria are _________________,
pathogens
which means they cause disease.
anthrax
diptheria
Some diseases caused by bacteria are: _____________,
_________________,
tetanus
whooping
cough
Lymes
_________________,
______________
____________,
_____________
strep
throat
_______________,
and ________________
________________.
These diseases
disease
antibiotics
are treated with _______________________
which kill bacteria, some by preventing
cell
walls
the bacteria from making their _________
__________
(Ex: penicillin). Some
toxin
bacteria produce a ______________
which is poisonous (Ex: botulism, a form of
food
poisoning
____________
________________).
Harmful bacteria can be killed through
pasteurization
____________________,
which heats food up to a high temperature
milk
fruit
juices
(as in ____________
and ___________
____________).
Draw the 3 shapes of bacteria below and label them with their name and shape.
Cocci - spherical
Bacilli – rod-shaped
Spirilla – spiral shaped
