1 Classification of Living Things
Six Kingdoms Classification of Living Things

2 Classification Arrangement in classes or groups to help scientists.
Factors used to classify organisms They have similar structures They have similar behaviors They acquire energy the same way or eat the same things They have the same chemical make-up

3 Three Domains At the broadest level, all living things seem to be related by ancestry to one of the 3 major lineages, Domains Archaea Bacteria Eukarya

4 Three Domains Archaea (scientists believe they are the first cells)
Simple single celled Prokaryotic Inhabit harsh environments Deep sea vents Sulfurous hot springs Waste water Salt lakes Produce flammable gases such as methane

5 Three Domains Bacteria Simple single-celled Prokaryotic Cell wall
Cell membrane Reproduce by binary fission

6 Three Domains Eukarya Consists of eukaryotic organisms
Some single celled some multicellular Large cells with a nucleus and organelles Includes plants animals, fungi and protists

7 Six Kingdoms of Living Things
Archeabacteria (ancient bacteria) Eubacteria (true bacteria) Protists Fungi Plants Animals

8 Archaebacteria Cell Type Cell surface Body plan Nutrition
Prokaryotic –lack a true nucleus and other organelles Cell surface cell wall lacks peptidoglycan, cell membrane has no fatty acids Body plan unicellular Nutrition sometimes heterotrophic, sometimes autotrophic/chemosynthesis

9 Archaebacteria Example – Halophilic bacteria Thermophilic bacteria

10 Eubacteria Cell type – Cell Surface Body Plan Nutrition prokaryotic
cell wall contains peptidoglycan, cell membrane contains fatty acids Body Plan unicellular Nutrition heterotrophic, sometimes autotrophic by photosynthesis or chemosynthesis

11 Eubacteria Staphylococcus Examples E. coli Cyanobacteria

12 Protists Cell Type Cell Surface Body Plan Nutrition
Eukaryotic – contain nucleus and organelles Cell Surface Cell wall made of cellulose, cell membrane contains fatty acids Body Plan Unicellular Rarely multicellular Nutrition Autotrophic – by photosynthesis Heterotrophic - phagocytosis

13 Protists Amoeba Example Paramecium Algae

14 Fungi Cell Type Cell Surface Body Plan Nutrition
Eukaryotic – contain nucleus and organelles Cell Surface Cell wall contains chitin Cell membrane contains fatty acids Body Plan Unicellular multicellular Nutrition Heterotrophic – by digestive enzymes

15 Fungi Examples

16 Plants Cell Type Cell Surface Body Plan Nutrition
Eukaryotic – contain nucleus and organelles Cell Surface Cell Wall contains cellulose Cell Membrane contains fatty acids Body Plan Multicellular Nutrition Autotrophic

17 Plants Examples Succulants Flowering plants Conifers Ferns Mosses

18 Animals Cell Type Cell Surface Body Plan Nutrition
Eukaryotic – contain nucleus and organelles Cell Surface No Cell Wall Cell membrane contains fatty acids Body Plan Multicellular Nutrition Heterotrophic

19 Animals Examples Mammals Amphibians Arthropods Bony Fish Marsupials
Reptiles Insects

20 Quiz An unknown organism has been found in a remote place on Earth. Scientists have found that the organism makes its own food, its cells have a nucleus and it is multicellular. To which Kingdom does this organism belong? An unknown unicellular organism was found growing on the side of a volcano. It smells really bad and glows a bright purple! Microbiologists have found that it eats sulfur for energy. Under the microscope, DNA was found but no true nucleus. To which Kingdom does this organism belong?

When a taxonomist discovers a new organism they start classifying it based on certain characteristics…..first, they look at what kind of cell structure.
