1. Taxonomy!!

2.  Taxonomy!  Branch of biology used to classify organisms according to their characteristic similarities  Consider phylogeny (evolutionary history) relationships of organisms' structures (Morphology, reproduction, nutrition)  A man made science How do humans bring order to the diversity of life existing today??

3.  Ancient Greek Philosopher. Devised system of classification based on organism behavior and structure. Aristotle

4.  Swedish Naturalist (1707-1778) Carolus Linnaeus

5.  Organisms grouped according to morphology into hierarchal categories. (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species)  Classification of Organisms is from general to specific  Final two categories (genus species) created a scientific method of naming organisms. Linnaeus System

6.  Two word system of naming organisms  Genus & species  Use Latin to assign a single identifying name to every discovered organism  Genus is Capitalized and species is not  Written in italics or underlined Binomial Nomenclature

7. Have you ever eaten dolphin? Common Name: Dolphin Common Name: Mahi-Mahi, Dolphin Scientific name: Tursiops truncatus Coryphaena hippurus Why have a universal language of scientific names?

8. Biological Hierarchy of Classification

11.  Primitive single celled prokaryotic organisms, have cell walls with no peptidoglycan, adapted to extreme conditions, may be autotrophic or heterotrophic Archeabacteria

12.  Single-celled prokaryotic organisms that have cell walls with pedidoglycan, autotrophic or heterotrophic Eubacteria

13.  Bacteria is the oldest organism ever!  The belong to the kingdom MONERA  All bacteria have NO NUCLEUS, which means that their DNA could be floating all around the cytoplasm. Bacteria

14.  Bacterial DNA is arranged in a CIRCULAR shape (plasmid)  Bacteria are just like people, they come in all different shapes and sizes. The three shapes are : 1.ROD 2.SPIRAL 3.ROUND

15.  Diverse group of eukaryotes, mostly unicellular, can be animal like heterotrophy, protozoans (zooplankton) or plant-like autotrophs algae (phytoplankton) Protista

16. If you look at a drop of pond water under a microscope, all the "little creatures" you see swimming around are protists. Protists are very diverse in how they acquire food and energy. Protozoa : heterotrophs which feed on other plants and animals. Algae: autotrophic protists, (make their own food)

17. Phylum- Rhizopoda Phylum-Foraminifera Phylum-Chlorophyta Phylum- Rhodophyta

18. Phylum-Phaeophyta Phylum-Bacillariophyta

19.  Non-motile, mostly multicellular, eukaryotic heterotrophs, have cell walls containing chitin. Fungi

20.  Multicellular eukaryotic chloroplast containing autotrophs, have cell walls containing cellulose. Plantae

21.  Multicellular, eukaryotic heterotrophy lacking cell walls, primarily sexual reproducers, most show some level of anatomical organization with specialized cells. Animalia
