1. & Unit 4:

2. Objectives: 1.Know the founder of classification. 2. Know the seven levels of classification. 3. Know how to name organisms using scientific names 4. Know how to use a Dichotomous Key to identify organisms. 5. Know the names of the five kingdoms. 6. Know the five main characteristics of each kingdom.

3. Classification The arrangement of organisms into orderly groups based on like physical characteristics. Physical characteristics: Observable traits. (Things that you can see) Examples: Color, number of legs, wings present, size (measured) The following are not physical characteristics: can fly, swim, talk, walk

4. Taxonomy The science of identifying, classifying and naming organisms. Carolus Linnaeus discovered taxonomy during the 1700’s. He tried to classify organisms using like characteristics.

5. Levels of Classification Kingdom Phylum Class Order Family genus species Organisms are classified into smaller and smaller groups. Greatest number (Inclusive) Smallest number (Exclusive) Hint to remember 7 levels King Philip Came Over For Grape Soda

6. Using the seven levels of classification

8. Naming Organisms Organisms are normally called by common names. (Ex. Human) All Organisms also have a scientific name. An organism’s scientific name comes from the Genus and species of the classification system. Example: A human’s scientific name is Homo sapien or Homo sapien (Italics) Scientific names are usually Greek or Latin.

11. Dichotomous Key Used as a way of identifying organisms. Descriptive questions are asked about the organisms physical characteristics, usually with yes or not answers. They can look like a flow chart or a numbered list of questions.

13. The Five Kingdoms All living things (organisms) can be placed in one of five kingdoms: Bacteria (monera) Protists (Protista) Fungi Plants (Plantae) Animals (Animalia)

14. Main Characteristics Kingdom Monera (bacteria) One celled organisms (unicellular) Contain a cell wall Do NOT have a nucleus (Prokaryotic) Most do not move on their own Obtain energy by feeding off of dead organisms (decomposers)

15. Main Characteristics Kingdom Protista (protists) Most are unicellular, some are multicellular (more than one cell) Do NOT contain a cell wall Do have a nucleus (Eukaryotic) Some move on their own Some obtain energy by making their own food (producers), some are decomposers and other obtain food (consumers).

16. Main Characteristics Kingdom Fungi Most are multi-cellular, a few are unicellular. Contain a cell wall Do have a nucleus (Eukaryotic) Do not move on their own Obtain energy by feeding off of dead organisms (decomposers)

17. Main Characteristics Kingdom Plantae (Plants) Multi-cellular organisms Contain a cell wall Do have a nucleus (Eukaryotic) Do not move on their own Obtain energy by making their own food (producers)

18. Main Characteristics Kingdom Animalia (Animals) Multi-cellular organisms Do Not contain a cell wall Do have a nucleus (Eukaryotic) Move on their own from place to place Obtain energy by eating other organisms (consumers)
