1) Define the important terms below:
a) Classification The grouping of things according to similar characteristics
b) Taxonomy a method of classifying organisms according to natural relationships
c) Taxonomist a scientist who studies the classification of living things
d) Binomial Nomenclature a two name system for naming organisms
e) Eukaryotic describes cells that have a true nucleus which surround and protects
the DNA
f) Prokaryotic describes cells that do not have a nucleus – the DNA just floats
around in the cytoplasm
g) Heterotroph (consumer) An organism that feeds on other organisms to obtain
nutrients
h) Autotroph (producer) An organism that makes its own food through
photosynthesis
i) Decomposer An special type of consumer that feeds on the remains of dead
organisms
Early Classification Systems
2) Aristotle classified all organisms into 2 kingdoms. What are those two kingdoms?
Plants and Animals
3) What are 2 major problems with this system of classification?
o There are organisms that do not fit into any category
o There are organisms that fit into multiple categories
o Organisms that are not related wind up in the same category
Binomial Nomenclature
4) What is the name of the scientist who came up with binomial nomenclature?
Carolus Linnaeus (Carl von Linne)
5) What are the rules when typing and writing by hand in binomial nomenclature?
o
o
o
o
Write the genus and species name next to each other
Capitalize the first letter of the genus & lower case the rest
Lower case the entire species
If handwriting, then underline – If typing, then italics
6) Why is binomial nomenclature a useful way to name organisms?
It solved the problem of organisms having multiple names in different parts of
the world
7) Write the scientific names below in the correct binomial nomenclature format.
A) Apis mellifera
B) Felis concolor
C) Canis lupis

10) State 4 ways how bacteria can be helpful and 2 ways it can be harmful.
Helpful
Harmful
Make oxygen
Spoil food
Make certain foods
Act as decomposers
Act as probiotics in supporting your
digestive system
Make you sick (cause illness and disease)
11) Why do we refer to archaea as chemotrophic? They use chemicals in their
environment to make food
12) What is a hydrothermal vent? A location on the ocean floor where super-heated
water is released into the ocean. This is where archaea live.
13) State the name of each protista on lines A, B, & C
Label the cell structure each protista uses for movement on lines D, E, & F
Draw a * next to the protist that is an autotroph (producer).
