2.1

 I can compare and contrast living and non- living things  I can explain the current classification system of 3 domains and 6 kingdoms  I can describe the similarities and differences between living things in different kingdoms

Living Things 1.Made of cells 2.Carry out basic life activities 3.Grouped into Kingdoms Plant Fungi Protist Archea Bacteria Animal Eubacteria

 A property is a quality that describes an object  Properties can describe how an object looks or feels  Properties can also describe how an object acts  We observe properties (sight, touch, smell, taste)  Examples: A property of a rock is its hardness A property of a person is their eye color

 Properties:  Color  Texture  Mass  Density  Shape  Size (height/weight)  Metallic Luster  Malleable  Smell  Taste

 Carry out basic life activities  Can move  Grow, develop, and reproduce  Called organisms  Do not carry out basic life activities  Do not move by themselves  Do not develop, grow or reproduce  Not made of cells

 An organism is any living thing that can carry out basic life activities  A complete, individual living thing

 Organisms:  _______________________________

 What are the 7 basic life activities?  1. Growth  2. Development  3. Getting food  4. Using food and removing wastes  5. Reproduction  6. Sensing and Responding  7. Movement

2.2

 Living things are more like one another than they are like non-living things  Example: They all carry out basic life activities  However, living things are also very different from one another  Example: A cat is different from a dog

 All living things are divided into a classification system:  Kingdom (King)  Phylum (Philip)  Class (Claimed)  Order (Only)  Family (Five)  Genus (Gold)  Species (Shoes)

 Taxonomy means classification  All living things stem from a common ancestor  Carl Linnaeus developed an organization system in 1758  His system only had two kingdoms: Plant and Animal  This system stayed unchanged until the 1960’s

 In 1969, Thomas Whittaker proposed a 5 kingdom system  He added Fungus, Protist and Monera to the existing kingdoms Plant and Animal  Whittaker defined the kingdoms on the basis of if they possessed a true nucleus (eukaryotic)  Monera do not possess a true nucleus (prokaryotic)  The other 4 kingdoms are eukaryotic

 New evidence supports that the 5 kingdom system is not correct  As more and more unicellular organisms are being discovered, these organisms also appear to be prokaryotic (no true nucleus)  These organisms did not fit into the Monera kingdom at all  In the 1980’s, Carl Woese proposed a radical reorganization of the 5 kingdoms into 3 domains

 Carl Woese’s design has been increasingly accepted by biologists over the years  It is now the standard theory  In his system, Woese placed all 4 eukaryotic kingdoms into one, single domain called Eukarya  Then, he split the Monera Kingdom into 2 Domains: Eubacteria (bacteria) and Archaea (archaebacteria)  He also placed most of the “unusual” prokaryotes (no true nucleus) in Archaea

 The plant and animal kingdoms were demoted as individual kingdoms  They are now within a domain  This is consistent with recent discoveries of more diversity among microbes  Woese’s 3 Domain system organizes biodiversity by evolutionary relationships rather than properties
