1 Bell Ringer: 8.20.2014 2. What are two types of eukaryotic cells?
1. Describe the difference in a prokaryote and a eukaryotic cell. 2. What are two types of eukaryotic cells?

2 Name 3 characteristics of life.
Bell Ringer: Name 3 characteristics of life.

3 What makes something living?
Organized: cells Acquire materials and energy Maintain homeostasis Respond to environment Reproduce Adapt to world around them Universal genetic code Grow and develop

4 Classification of Life
List each of the major levels in the hierarchy of taxa: kingdom, phylum, class, order, family, genus, species. Explain binomial naming system. Compare major divisions of vertebrates and invertebrates.

5 What is taxonomy? Based on how organisms are related to one another.
Definition: branch of biology concerned with identifying naming, and classifying organisms. There are 13 billion known species of organisms This is only 5% of all organisms that ever lived!!!!! New organisms are still being found and identified

6 Why do organisms need specific names?
Different countries use different languages Same language, but different common name Therefore, we must use a universal language.

7 Carolus Linnaeus 1707 – 1778 Called the “Father of Taxonomy”
Developed the modern system of naming known as binomial nomenclature Two-word name (Genus & species) 18th century taxonomist Classified organisms by their structure Developed naming system still used today

8 Binomial nomenclature
Two part naming system for identify species. Bi-two nomial-name First word is genus (classification category that contain species) Second word is species (one specific species in the genus group) Each name tell us something about the organism. Scientific name : genus is capitalized and species is not. But both are italicized.

9 Classification Categories
Taxonomists use the following major categories of classification. Domain Kingdom Phylum Class Order Family Genus Species Broadest classification Most specific

11 Domain Classification
Broadest, most inclusive taxon Three domains Archaea and Bacteria are unicellular prokaryotes (no nucleus or membrane-bound organelles) Eukarya are more complex and have a nucleus and membrane- bound organelles copyright cmassengale

12 ARCHAEA Kingdom - ARCHAEBACTERIA Probably the 1st cells to evolve
Live in HARSH environments Found in: Sewage Treatment Plants (Methanogens) Thermal or Volcanic Vents (Thermophiles) Hot Springs or Geysers that are acid Very salty water (Dead Sea; Great Salt Lake) - Halophiles copyright cmassengale

13 ARCHAEAN copyright cmassengale

14 BACTERIA Kingdom - EUBACTERIA Some may cause DISEASE
Found in ALL HABITATS except harsh ones Important decomposers for environment Commercially important in making cottage cheese, yogurt, buttermilk, etc. copyright cmassengale

15 Live in the intestines of animals

16 Domain Eukarya is Divided into Kingdoms
Protista (protozoans, algae…) Fungi (mushrooms, yeasts …) Plantae (multicellular plants) Animalia (multicellular animals) copyright cmassengale

17 copyright cmassengale

18 copyright cmassengale

19 Animalia Kingdom Phylum: Annelida- earthworms Nematoda- roundworms
Platyhelminthes- tapeworms Porifera- sponge Cnidaria- jellyfish, sea anemones, corals Echinoderma- sand dollars, starfish Molluska- snails, clams, oysters, octopuses Arthropoda- spiders, scorpions, carbs, insects Chordata Class: Fish (chondrichthyes and osteichthyes) Amphibia- frogs, toads, salamanders Reptilia- snakes, lizards, turtles Aves- birds Mammalia- mammals (cats, dogs, horses)
