Classification/Taxonomy
1. Taxonomy is the science of grouping and naming organisms based on _________________________
_______Shared characteristics; their shape and structure______________________________________
Contributions to Classification/Taxonomy:
Aristotle
Linnaeus
- First to classify living things
- Founded modern taxonomy
- Divided living things into 2 groups
(animals and plants)
- Classify living things based on shape and
structure
- Swedish scientist (1700s)
- System used today is similar
2. Put the taxa in the correct order from largest (most kinds of organisms) to smallest (one kind of organism)
CLASS, DOMAIN, GENUS, FAMILY, KINGDOM, ORDER, PHYLUM, SPECIES

______________Phylum________________________
________________Class________________________
_______________Order________________________
______________Family_________________________
______________Genus_________________________
______________Species________________________
3. Members of the same ___Species________ can mate and produce fertile offspring.
4. Taxonomists use a two part naming system to identify an organism. The scientific name of an
organism is the ___genus_______ and _____species_________ of the organism.
5. This system of naming is called___taxonomy (Binomal Nomenclature)______________
Domains: The tree of life groups all living organisms based on evolutionary relationships into large,
inclusive groups, primarily based on the presence or absence of a nucleus within the cell. The largest
taxonomic group is called the domain. The two groups of prokaryotic organisms are so different from
each other that they are grouped into different domains. So the original concept that all bacteria
(prokaryotic organisms) should be classified in the same kingdom (called Monera) has been altered. The
three domains are: Archea (prokaryotic), Bacteria (prokaryotic) and Eukarya (includes the kingdoms
Protista, Fungi, Plantae and Animalia).
Characteristics of the Different Kingdoms
Use the word bank to put the information in the correct kingdom categories on the following page.
(Terms may be used more than once)
Cell Number: Unicellular or multicellular
Cell type: Prokaryotic or eukaryotic, Cell Walls or No Cell Walls
Nutrition: How does it get food/nutrients? (chemosynthesis, photosynthesis, absorbs nutrients from dead
or decaying animals, depends on plants for food)
Locomotion: How does it move? Does it move?
Examples: List as many examples from the kingdom as you can
(oak tree, moss, eagle, sulfolobus, yeast, slime molds, moss, sponge, human, streptococcus, cordyceps,
mushrooms, grass, thermophiles, staphylococcus aureus, euglenoids, mildew, jellyfish, E. coli)
