Title: Classification and Biodiversity


1
Classification and Biodiversity
2
  • About _1.5 million___ kinds of living organisms
    are known today and each year thousands more are
    identified.
  • Some experts believe there are as many ___10
    million_ different kinds of organisms.

3
Taxonomy
  • Classification and naming of living things.

4
Classification Systems
  • How is a grocery store classified/ organized?

5
Early classification
  • Aristotle
  • Classified organisms by how they moved.
  • Fly
  • Walk
  • Swim
  • Problems?

6
  • John Ray
  • First to use the term Species.
  • Classified based on structural similarities

7
  • Carolus Linnaeus
  • Father of modern taxonomy.
  • Developed naming system of binomial nomenclature

8
Classification Categories
  • Kingdom Animalia
  • Phylum Chordata
  • Class Mammalia
  • Order Primates
  • Family Hominidae
  • Genus Homo
  • Species Sapiens

11
Naming organisms
  • Nomenclature naming organisms

12
  • Common name vs. scientific name
  • There may be many common names for one organism.
  • Puma, cougar, mountain lion
  • Only one scientific name.
  • Felis concolor

13

14
Binomial Nomenclature
  • Hedera helix or Hedera helix
  • Italicize or underline scientific name
  • Hedera genus
  • helix species

16
Characteristics of the 6 kingdoms
  • Monera bacteria
  • Cell type prokaryotic
  • Body form mostly unicellular

17
  • How they get energy
  • Photosynthesis
  • Absorption
  • Chemosynthesis
  • No nervous system
  • Locomotion some have flagella

18
Protista
  • Cell Type Eukaryotic
  • Body Form Mostly unicellular
  • Energy Some photosynthesis, some
    respiration/absorption
  • No nervous system
  • Locomotion
  • Flagella whip like tail
  • Cilia tiny hairs
  • Pseudopods fake feet/ oozing cytoplasm

19
Fungi
  • Cell type Eukaryotic
  • Body form mostly multi-cellular
  • Energy from decomposition/absorption
  • No nervous system
  • No locomotion

20
Plantae
  • Cell type eukaryotic
  • Body form multi-cellular
  • Energy photosynthesis
  • No nervous system
  • Little locomotion

21
Animalia
  • Cell type eukaryotic
  • Body form multi-cellular
  • Energy cell respiration/ingestion
  • Yes, have nervous system
  • Yes, locomotion walk, swim, fly

22
Monera
  • Bacteria is the common name for members of this
    kingdom.
  • Where can bacteria be found? Everywhere!

23
Bacteria shapes
  • 1. Round (cocci)
  • 2. Rod-shaped (bacillus)
  • 3. Sprial

24
Two groups of bacteria
  • 1. Archaebacteria ancient bacteria
  • Adapted to unusual and/or extreme conditions,
    such as very hot, very salty, or no-oxygen
    environments. Have several different cellular
    chemistries from Monera
  • 2. Eubacteria (monera) true bacteria most
    bacteria are this type

25
Examples of bacteria and good things bacteria do
  • Watch movie

  • Stentor
  • Vorticella
  • Paramecium
  • Amoeba

29
Plant like protists
  • Algae green, red, brown
  • Spirogyra
  • Volvox
  • Diatoms
  • Euglena

30
Fungus-like protists
  • Slime-molds

31
Watch movie
  • Feeding styles of protists
