1. CLASSIFICATION Of
LIVING THINGS

2. WHAT IS CLASSIFICATION?
SORTING LIVING THINGS INTO GROUPS BASED ON THEIR SIMILARITIES
WHY?

3. We classify because:
Diversity creates a need to classify, so we…...
Sort living things into categories to…...
understand characteristics of living things.

4. CLASSIFY LIVING THINGS ANIMALS PLANTS Leaves Fur No Fur All Lose year

5. Taxonomy - the scientific study of how things are classified.

6. ARISTOTLE
Made the first system of classification

7. Carolus Linnaeus made today’s classification system.
Binomial nomenclature: 2 part name based on shared characteristics.
CANIS LUPUS

8. lUPUS CANIS Genus is a classification grouping that contains
The first part of the organism’s scientific name is its genus & it is capitalized.
Genus is a classification grouping that contains
similar, closely related organisms.
lUPUS
CANIS

9. The 2nd part is the Species and it is lower case
Recall, species are organisms that can mate and produce offspring
CANIS
lUPUS

10. Why would you want to classify organisms ??

11. TO MAKE THINGS EASIER!

12. Taxonomic Key or dichotomous key
A series of paired statements that describe physical characteristics of organisms

13. TWO DOMAINS:
ARCHAE & EUKARYA

14. Seven Levels of Classification:
Example of lion classification
Domain
Kingdom animals Animalia
Phylum backbone Chordato
Class mammal Mammalia
Order carniovre Carnivora
Family feline Felidae
Genus panther Panthera
Species lion Leo

15. OR create ur own! How do u remember the 7 levels?
Use one of these mnemonics:
Domain Do Do
Kingdom Kings Kids
Phylum Play Put
Class Chess Catsup
Order On On
Family Flat Fried
Genus Glass Garlic
Species Surfaces Sandwiches
OR create ur own!

16. Living things grouped in 6 kingdoms:
Archaebacteria
Kingdom
Eubacteria
Kingdom
Protista

17. Kingdom Fungi
Kingdom Plantae
Kingdom Animalia

18. Archaebacteria
Unicellular organisms
that already existed billions
of years before the dinosaurs. Scientist’s think they were the earliest form of life.

19. Archaebacteria
Live in extreme environments and can survive where no other organisms can.
Unicellular
Prokaryotes

20. Eubacteria These bacteria are constantly on & around us.
Good (in yogurt) & bad (strep throat) bacteria
Unicellular
Prokaryotes

21. 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.

22. 3 shapes of bacteria
Bacillius – rod shaped
Coccus – spherical
Sprillia - spiral

23. PROTISTS
Have u ever walked on the beach and seen tangled piles of seaweed?
Protist kingdom is called the odds and ends kingdom
Some r autotrophs, some r heterotrpohs - most r unicellular but a few like seaweed r multicellular

24. FUNGI Mushrooms, molds and mildews Multicellular heterotrophs
eukaryotes
Mushrooms, molds and mildews
Exception: yeast is unicellular
Most feed on dead & decaying organisms

25. PLANTS:
vascular & non-vascular
gymnosperms
angiosperms

26. ANIMALS Multicellular Eukaryotes
Dog, flea cat cow, monkey, wasp, tarantula, human, fish, worm, etc.

27. THINK ABOUT IT...

28. What name do we give bacteria?
A. Eukaryote
B. Prokaryote

29. Why do scientists classify organisms?
A. For organization
B. To determine where new organisms fit in
C. A and B

30. What is the genus and species name for man?
A. Homo Sapiens
B. Homo Erectus
C. Homozygote

31. 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

32. Which kingdom consists of:
Molds?
Seaweed?
Yeast?
Helpful bacteria?
fungi
protist
