Title: CLASSIFICATION OF LIVING THINGS CHAPTER 2


1
CLASSIFICATIONOF LIVING THINGS CHAPTER 2

Bell Ringer 9/4/14
  • Think about different ways you classify things.
    List four groups of things that humans classify,
    such as library books. What happens when you put
    something in the wrong group? Can objects or
    ideas belong in more than one group?

3
ObjectivesSPI 0807.5.1
  • Explain why and how organisms are classified.
  • List the eight levels of classification.
  • Explain scientific names.
  • Describe how dichotomous keys help in identifying
    organisms.

4
Classification
  • means organizing living things into groups based
    on their similarities.

5
Why Classify?
  • The classification of living things makes it
    easier for biologist to answer important
    questions such as
  • 1. How many known species there are?
  • 2. What are the defining characteristics?
  • 3. What are the relationships between
    these species?

6
Early Classification systems
  • Aristotle grouped animals according
  • to the way they moved

7
Scientists classify
  • living and extinct organisms to make them easier
    to study.

8
Organisms are classified by
  • shared characteristics and their relationships
    between one another.

9
  • The levels of classification go from very general
    to very specific.

The 8 levels (pneumonic device)
  • Domain..................................Did
  • Kingdom...............................King
  • Phylum..................................Philip
  • Class.......................................Come
  • Order......................................Over
  • Family.....................................For
  • Genus.....................................Grape
  • Species....................................Soda

12
  • The science of classifying organisms is called
    taxonomy.

13
  • Taxonomy was founded by Linnaeus in the 1700s.
  • He classified things only by their shared
    characteristics.

14
Modern Taxonomists Researchers
Look at evolutionary relationships between
animals
Recently found, buried Antarctic lake teems with
new life. Microbes living a lake deep under ice.
Biologists found these new living cells that have
been living in the lakes pitch-black water at a
frigid temperature of 0.49 degrees Celsius (31.1
degree Fahrenheit).
15
  • A branching diagram can show relationships
    between organisms.
  • Organisms that are more closely related are
    closer together on the branching diagram.

16
Branching diagrams
Listen carefully. You will be practicing this in
groups next.
17
  • When living things are classified, they get a
    scientific name.
  • The scientific name is the same anywhere in the
    world.

18
The 4 Rules to writing a Scientific Name
  • 1. Scientific names are usually Latin or Greek.
  • 2. The scientific name is always the genus and
    species name together.
  • 3. The genus is always written first and
    capitalized. The species is second and is always
    lower case.
  • 4. The scientific name is always italicized or
    underlined.
  • Example Felis domesticus

19
  • Lion Tiger
  • Kingdom Animalia Animalia
  • Phylum Chordata Chordata
  • Class Mammalia Mammalia
  • Order Carnivora Carnivora
  • Family Felidae Felidae
  • Genus Panthera Panthera
  • Species leo tigris

?With your elbow partner decide what is the same
about the lion and tiger? What is different?
20
Domains and Kingdoms
  • Bacteria are prokaryotic, meaning they do NOT
    have a nuclei.
  • All other living things are eukaryotic and have
    nuclei.

21
Scientists use 3 Domains
  • Archaea
  • Bacteria
  • Eukarya

Prokaryotes (no nucleus, single-celled organism)
Eukaryotes (have nucleus)
22
Scientists use 6 Kingdoms
  • 1. Archaebacteria
  • 2. Eubacteria
  • 3. Protista
  • 4. Plantae
  • 5. Fungi
  • 6. Animalia

23
Domain ArchaeaKingdom Archaebacteria
  • Live in extreme environments (very hot or cold).
    They have been on earth for about 3 billion
    years.

24
Domain BacteriaKingdom Eubacteria
  • Most bacteria live in Kingdom Eubacteria. They
    live in many place all over earth and even inside
    other organisms.

E. Coli lives in the intestines of animals and
decompose undigested food.
25
Domain EukaryaKingdom Protista
  • Consists of unicellular and simple multicellular
    organisms. Protista includes organisms that are
    not plants, animals, or fungi.

Paramecium
Zooflagellates
26
Domain EukaryaKingdom Plantae
  • Plants are usually green and make food by
    photosynthesis. They are complex, multicellular
    organisms.
  • In this kingdom, live the oldest unitary
    organisms in the world...

BRISTLECONE PINE
Known to surpass 5,000 years in age.
28
GIANTSEQUOIAThis tree is no longer considered
the longest living tree, but may someday because
they live forever. Only dying when an external
physical event kills the, e.g. fire or erosion.
Oldest sequoia tree today 3,300 years of age and
its the largest member of Plantae
29
Domain Eukarya Kingdom Fungi
  • They absorb food from their surroundings. Fungi
    are usually multicellular (except yeast).

30
Domain EukaryaKingdom Animalia
  • Most move around and have nervous systems.
    Animals are complex multicellular.

31
Talking Turtles!
  • Scientists study talking turtles in Brazilian
    Amazon.
  • "These distinctive sounds made by turtles give us
    unique insights into their behavior, although we
    don't know what the sounds mean," said Dr. Camila
    Ferrara, Aquatic Turtle Specialist for the WCS
    Brazil Program. "The social behaviors of these
    reptiles are much more complex than previously
    thought.

Giant South American river turtle. The turtle is
the largest member of the side-necked turtle
family and grows up to nearly three feet in
length.
