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. Carolus Linnaeus developed the system we use today.
All organisms are given a two part name based on shared characteristics.
CANIS LUPUS

7. 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

8. The 2nd part is the Species
Recall, species are organisms that can mate and produce offspring
CANIS
LUPUS

9. Why would you want to classify organisms ??

10. Taxonomic Key
A series of paired statements that describe physical characteristics of different organisms

11. 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

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

13. Kingdom Fungi
Kingdom Plantae
Kingdom Animalia

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

15. Archaebacteria
Live in extreme environments and can survive where no other organisms can.

16. 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.

17. Reproduction of bacteria
Some bacteria go through asexual reproduction, while others go through a form of sexual reproduction known as conjugation.

18. Asexual Reproduction
Binary fission
the cell duplicates
its genetic material
and then divides
with each cell gets
exactly the same
thing.

19. 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.

20. THINK ABOUT IT...

21. What name do we give bacteria?
A. Eukaryote

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

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

24. 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
