WHAT IS CLASSIFICATION?
SORTING LIVING THINGS INTO
GROUPS BASED ON THEIR
SIMILARITIES
WHY?
We classify because:
•Diversity creates a need to classify, so we…...
•Sort living things into categories to…...
•Understand characteristics of living things.

TaxonomyTaxonomy - the scientific study of how things are classified.
Carolus Linnaeus developed the system we use today.
All organisms are given a two part name based on shared characteristics.
CANIS LUPUS
The first part of the organism’s scientific name is its genus.
Genus is a classification grouping that contains similar, closely related organisms.
CANIS LUPUS
The 2nd part is the Species
CANISLUPUS
Recall, species are organisms that can mate and produce offspring
Why would you want to classify organisms ??
Taxonomic Key
A series of paired statements that describe physical characteristics of different organisms
Seven Levels of Classification:
Kingdom animals Animalia
Phylum backbone Chordato
Class mammal Mammalia
Order carniovre Carnivora
Family feline Felidae
Genus panther Panthera
Species lion Leo
Example of lion classification
Living things grouped in 6 kingdoms:

Archaebacteria
Unicellular organisms that already existed billions of years before the dinosaurs. Scientist’s think they were the earliest form of life.
Archaebacteria
Live in extreme environments and can survive where no other organisms can.
EubacteriaThese bacteria are constantly on & around us. Eubacteria use the sun’s energy to produce oxygen, helping keep the Earth’s oxygen at the proper level.
Reproduction of bacteria
Some bacteria go through asexual reproduction, while others go through a form of sexual reproduction known as conjugation.
Asexual Reproduction
Binary fissionthe cell duplicatesits genetic material and then divides with each cell gets exactly the same thing.
Obtaining FoodObtaining Food
Some bacteria are autotrophic autotrophic and make their own food the same way plants do. Others are heterotrophicheterotrophic which means they consume a variety of foods from milk to meat.
