binomial nomenclature
SB3b
Compare how structures and function vary between the six kingdoms (archaebacteria, eubacteria, protists, fungi, plants,
and animals).
CLASSIFICATION is putting things into orderly groups based on similar
characteristics.
The science of describing, classifying, and naming living things is called TAXONOMY.
Aristotle (late 300’s B.C.) Classified based on air, land, or water dwellers.
Before the 1600s Two groups: plants and animals.
Carolus Linnaeus Founded taxonomy in the 1700s.
He sorted things based on their shape and structure.
First to use binomial nomenclature
Today Eight-level system to classify living things.
Domain (largest and most general group)
Kingdom
Phylum
Class
Order
Family
Genus
(smallest group; organisms can mate and reproduce) Species
Didn’t King Phillip Come Over For Good Spaghetti?
When a scientist wants to classify an organism, he/she must first determine the organism’s DOMAIN.
There are currently three domains: Archaea Bacteria Eukarya
Once placed in the correct domain, the kingdom is determined.
The scientist then determines the phylum, class, order, family, genus, and species of the organism IN THAT ORDER.
Binomial Nomenclature Two word naming system used to create scientific names
First word is the genus (capitalized)
Second word is the species (not capitalized)
Using scientific names eliminates confusion that may happen with
common names!

Into what kingdom would each of the following be classified:
a) unicellular prokaryotes that live in dustb) unicellular eukaryotes that live in pond waterc) multicellular eukaryotes that live all over the planet and consume foodd) unicellular prokaryotes that live in volcanic ash and other inhospitable environments
e) multicellular eukaryotes that have cell walls and are heterotrophic f) multicullular eukaryotes that have cell walls and are autotrophic

Would you expect an animal with the name Rania concolor to look similar to
a mountain lion? Why or why not?

Which animal is most closely related to the house cat?
Organisms that below to the same class, must belong to the same :
Order
Phylum
Kingdom
Family
In each pair, choose the one that you would expect to find the most individual species:
kingdom and genus
phylum and kingdom
phylum and class
class and family
