1. CLASSIFICATION & THE SIX KINGDOMS OF ORGANISMS

2. WHY DO SCIENTISTS CLASSIFY ?
Biologists Use Classification To Organize Living Things Into Groups So That Organisms Are Easier To Study

3. The Scientific Study Of How Living Things Are Classified
TAXONOMY
The Scientific Study Of How Living Things Are Classified

4. CAROLUS LINNAEU’S CLASSIFICATION SYSTEM
BASED ON PHYSICAL & STRUCTURAL SIMILARITIES
REFLECT THE EVOLUTIONARY RELATIONSHIPS OF SPECIES

5. SCIENTIFIC NAME  BINOMIAL NOMENCLATURE
The Naming System For Organisms In Which Each Organism Is Given A
Two-Part Name

6. SCIENTIFIC NAME  BINOMIAL NOMENCLATURE
1ST WORD = GENUS CAPITALIZED
2ND WORD = SPECIES
WRITTEN IN LATIN ;
IN ITALICS

7. KINGDOM  PHYLUM  CLASS  ORDER  FAMILY  GENUS  SPECIES
KINGDOM : BROADEST - LARGEST NUMBER OF SPECIES
SPECIES : NARROW SPECIFIC DESCRIPTION

9. DICHOTOMOUS KEY
A SERIES OF PAIRED STATEMENTS THAT DESCRIBE THE PHYSICAL CHARACTERISTICS OF DIFFERENT ORGANISMS

10. THE SIX KINGDOMS OF ORGANISMS
MAKE A TABLE THAT COMPARES THE CHARACTERISTICS OF MEMBERS OF EACH OF THE SIX KINGDOMS.

11. LIVE IN EXTREME ENVIRONMENTS.
1) ARCHAEBACTERIA
UNICELLULAR PROKARYOTES WITH STRONG CELL WALLS WHOSE CELLS LACK A NUCLEUS 
LIVE IN EXTREME ENVIRONMENTS.

12. 2) EUBACTERIA UNICELLULAR PROKARYOTES 
CELLS LACK DISTINCT NUCLEI BOUNDED BY A MEMBRANE.

13. 3) PROTISTS A DIVERSE GROUP 
A EUKARYOTE THAT LACKS COMPLEX ORGAN SYSTEMS AND LIVES IN MOIST ENVIRONMENTS.

14. 4) FUNGUS EARTH’S DECOMPOSERS 
UNICELLULAR OR MULTICELLULAR HETEROTROPHIC EUKARYOTES THAT ABSORB NUTRIENTS FROM ORGANIC MATERIALS IN THE ENVIRONMENT; DO NOT MOVE FROM PLACE TO PLACE.

15. 5) PLANTS MULTICELLULAR OXYGEN PRODUCERS 
PHOTOSYNTHETIC AUTROPHIC EUKARYOTES –
CONTAIN CHLOROPLASTS AND HAVE CELL WALLS COMPOSED OF CELLULOSE; NONE MOVE FROM PLACE TO PLACE.

16. 6) ANIMALS MULTICELLULAR CONSUMERS 
HETEROTROPHS – CELLS LACK CELL WALLS, NEARLY ALL ARE ABLE TO MOVE FROM PLACE TO PLACE.

18. CLASSIFICATION
THE PROCESS OF GROUPING THINGS BASED ON THEIR SIMILARITIES
(TO BETTER UNDERSTAND ORGANISMS)

19. THE SCIENTIFIC STUDY OF HOW LIVING THINGS ARE CLASSIFIED

THE SCIENTIFIC STUDY OF HOW LIVING THINGS ARE CLASSIFIED

20. BINOMIAL NOMENCLATURE
THE NAMING SYSTEM FOR ORGANISMS IN WHICH EACH ORGANISM IS GIVEN A TWO-PART NAME

21. GENUS
A CLASSIFICATION GROUPING THAT CONSISTS OF A NUMBER OF SIMILAR, CLOSELY RELATED SPECIES

22. SPECIES
A GROUP OF SIMILAR ORGANISMS WHOSE MEMBERS CAN MATE WITH ONE ANOTHER AND PRODUCE FERTILE OFFSPRING

23. TAXONOMIC KEY
A SERIES OF PAIRED STATEMENTS THAT DESCRIBE THE PHYSICAL CHARACTERISTICS OF DIFFERENT ORGANISMS

24. AN ORGANISM WHOSE CELLS LACK A NUCLEUS AND SOME OTHER CELL STRUCTURES
PROKARYOTE
AN ORGANISM WHOSE CELLS LACK A NUCLEUS AND SOME OTHER CELL STRUCTURES

25. AN ORGANISM WITH CELLS THAT CONTAIN NUCLEI AND OTHER CELL STRUCTURES
EUKARYOTE
AN ORGANISM WITH CELLS THAT CONTAIN NUCLEI AND OTHER CELL STRUCTURES

26. What did Linaeus contribute to the field of taxonomy?
HE DEVELOPED BINOMIAL NOMENCLATURE  A TWO-WORD NAMING SYSTEM FOR ORGANISMS

27. For what reasons are biological classification systems needed?
It is easier to study organisms and their relationships.

28. List the seven groups used in biological classification
List the seven groups used in biological classification. Which group contains the largest number of species? Which group contains the fewest?

29. Make a list of a minimum of five physical features you could use to classify trees.

30. How have technological advances, such as improved microscopes and new biological tests, changed biological classification.
Improved microscopes allow scientists to differentiate between prokaryotic and eukaryotic cells and among the cell organelles. Biochemical tests determine the presence of specific molecules in cells.
