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.
CLASSIFY LIVING THINGS ANIMALS PLANTS Leaves Fur No Fur All Lose year
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 organism’s scientific name is its genus.Genus is a classification grouping that contains similar, closely related organisms. LUPUS CANIS
The 2nd part is the SpeciesRecall, species are organisms that can mate and produce offspring CANIS LUPUS
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:Example of lion classification Kingdom animals Animalia Phylum backbone Chordato Class mammal Mammalia Order carniovre Carnivora Family feline Felidae Genus panther Panthera Species lion Leo
Living things grouped in 6 kingdoms:Archaebacteria Kingdom Eubacteria Kingdom Protista
Kingdom Fungi Kingdom Plantae Kingdom Animalia
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.
Eubacteria These 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 bacteriaSome 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 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
The science of naming organisms.
Characteristics of Living Things
For hundreds of years people have been trying to classify the species on our planet Earth There are potentially hundreds of thousands new species.
Chapter 9 Classification
The Six Kingdoms of Life. EUBACTERIA This is a kingdom of single-celled prokaryotes that have been around in similar forms since the beginning of life.
Classification. Classification of Living Organisms Identified by traits Organize life’s diversity – Over 1.7 million species on Earth Taxonomy Naming.
Chapter 18. Why Classify? ◦ Scientists classify organisms into groups in a logical manner to make it easier to study the diversity of life. ◦ Taxonomy:
ANIMALIA. kingdom of multicellular eukaryotic heterotrophs whose cells do not have cell walls.
Classification Chapter 18 Review Classification Chapter 18 Review.
Classification of Living Things
Kingdoms and Domains 18.3.
Protists Small in Size, Enormous in Diversity. Taxonomy Review What are the different groups a species is classified into? Kingdom Phylum Class.
Taxonom y a.k.a. Classification. Why do we classify things? We like things organized To have precise names of organisms Common names are too confusing.
+ Chapter 10 classification. + Sec 1: Classification: Sorting it All Out Classification – the arrangement of organisms into orderly groups based on their.
Diversity of Organisms 5 to 30 million species estimated Axolotl.
