Taxonomy and Scientific Classification
undefined
Taxonomy
Taxonomy:
The discipline of classifying
organisms and assigning each organism a
universally accepted (scientific name)
What is this animal called?
Cougar
Mountain Lion
Puma
Panther
Wait . . . So what do
we call it?!
Assigning Scientific Names
To eliminate the confusion
of common names, 18
th
century scientists
developed a system to
name all organisms in
Latin.
Binomial Nomenclature:
Each species is assigned a
two-part scientific name
EX:
Felis concolor
Scientific Names
Written in italics
The first word is capitalized
It is the organism’s genus
Genus:
A group of closely related species
The second word is lowercased
It is the organism’s species
Written in Latin
Answer this question in your
notes:
What is the difference, if any, between these
three organisms:
Ursus arctos
Ursus maritimus
Ailuropoda melanoleuca
Here’s a Hint:
Linnaeus’s System of
Classification
Includes seven levels, from largest to
smallest:
Kingdom
Phylum
Class
Order
Family
Genus
Species
Modern Classification
Linnaeus used to group organisms only by
their physical characteristics.
Using only physical characteristics, how
would you classify these organisms?
Modern Classification
Now, we use a 3 domain system because of
vast differences in different types of bacteria.
Current classification system:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
How Living Things are
Categorized
All living things are categorized into 3
domains
6 Kingdoms
3 Domains are further divided into 6
Kingdoms
Domain Archaea: Kingdom Archaebacteria
Domain Bacteria: Kingdom Eubacteria
Domain Eukarya:
Kingdom Protista
Kingdom Fungi
Kingdom Plantae
Kingdom Animalia

chart you were given into your INB. You can look over this
information while we go through the rest of the powerpoint.
Kingdom Archaebacteria
•
Cell Type:
Prokaryote (no nucleus)
•
Cell Structures:
Have unusual cell
wall components
•
Number of cells:
Unicellular
•
Mode of Nutrition:
Autotroph or
heterotroph
•
Examples:
Methanogens,
halophiles
Kingdom Eubacteria
Cell Type:
Prokaryote
Cell Structures:
No nucleus,
normal sugars in walls
Number of Cells:
Unicellular
Mode of Nutrition:
Autotroph or
Heterotroph
Examples:
E. coli, Streptococcus
Kingdom Protista
C
ell Type:
Eukaryote (has a nucleus)
Cell Structures:
Some have cell walls
of cellulose, some have
chloroplasts
Number of cells:
Unicellular or
multicellular
Mode of Nutrition:
Autotroph or
heterotroph
Examples:
Amoeba, Paramecium,
giant kelp, diatoms
Kingdom Fungi
Cell Type:
Eukaryote
Cell Structures:
Cell Wall of
Chitin
Number of Cells:
Multicellular,
some unicellular
Mode of Nutrition:
Heterotroph
Examples:
Mushrooms, yeasts
Kingdom Plantae
Cell Type:
Eukaryote
Cell Structures:
Cell walls
of cellulose, chloroplasts
Number of cells:
Multicellular
Mode of Nutrition:
Autotroph
Examples:
Mosses, ferns,
trees and flowering
plants
Kingdom Animalia
Cell Type: Eukaryote
Cell Structures: No cell
walls or chloroplasts
Number of cells:
Multicellular
Mode of Nutrition:
Heterotroph
Examples: Sponges,
worms, insects, fish,
mammals
