CLASSIFICATION Of LIVING THINGS
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.

Taxonomy Taxonomy - 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 organisms scientific name is its genus. Genus is a classification grouping that contains similar, closely related organisms. CANIS LUPUS
The 2nd part is the Species CANIS LUPUS 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 backboneChordato Class mammal Mammalia Order carniovreCarnivora Family feline Felidae Genus panther Panthera Species lionLeo Example of lion classification
Living things grouped in 6 kingdoms: Kingdom Protista KingdomArchaebacteria Eubacteria
Animalia Kingdom Animalia Plantae Kingdom Plantae Fungi Kingdom Fungi
Archaebacteria Unicellular organisms that already existed billions of years before the dinosaurs. Scientists think they were the earliest form of life.
Archaebacteria Live in extreme environments and can survive where no other organisms can.
Eubacteria These bacteria are constantly on & around us. Eubacteria use the suns energy to produce oxygen, helping keep the Earths 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 fission the cell duplicates its genetic material and then divides with each cell gets exactly the same thing.
Obtaining Food autotrophic heterotrophic Some bacteria are autotrophic and make their own food the same way plants do. Others are heterotrophic which means they consume a variety of foods from milk to meat.
THINK ABOUT IT...
What name do we give bacteria? A. Eukaryote B. Prokaryote
Why do scientists classify organisms? A. For organization B. To determine where new organisms fit in C. A and B
What is the genus and species name for man? A. Homo Sapiens B. Homo Erectus C. Homozygote
How do autotrophs and heterotrophs differ? A. One goes thru mitosis & the other does not B. One makes its own food and the other does not
