Blog post for period 4 on 2/14/11(Monday, February 14th)

Announcements- Invertebrate species project/poster due Tuesday February 22.

Be sure to get started on your friends of endangered species project.

Homework- Read chapter 18, section 3, and invertebrate species project due the 22nd

Today in class we started an new unit, called animal diversity. We took notes on the seven taxonomic groups, and kingdoms.

TAXONOMY-The study and science of classification and naming organisms.

7 Taxonomic groups

1.Kingdom- most diverse

2.Phylum

3.Class

4.Order

5.Family

6.Genus

7. Species-least diverse, many similar characteristics

Naming System-

1.Binomial nomenclature- two names comprised of genus and species

2.Names are in Latin-Never changing language

3.Example- Rana clamptons

4.Developed by Carolus Linnoeus

After the notes on Taxonomy and all of the classifications we moved on to different kingdoms, those kingdoms being,

A.Monera-prokaryotic cells, used to be one kingdom, split in two.

1.Archeabacteria- Single celled, prokaryotic, cell walls with peptidoglycan, live in harsh enviornments

2.Eubacteria- Single celled, prokaryotic, cell walls with peptidoglycan, most bacteria

B.Protista- most unicellular, Eukaryotic, heterotroph or autotroph. Examples- Amoeba, algae

C.Fungi- Unicellular or multicellular, Eukaryotic. Example- yeast

D.Plantae- Multicellular, Eukaryotic, autotroph, cells of cellulose. Examples- plants

E.Animalia-Multicellular, Eukaryotic, Heterotroph, no cell wall. Examples- animals
