1. Classification 7 th Science Ely, Hoyman, Jackson

2. Why Classify? Classification: the division of organisms into groups, or classes, based on specific characteristics. Classifying helps us to understand and order the many kinds of living things. Scientist group things by a system called Taxonomy. o Taxonomy is the science of describing, naming, and classifying organisms

3. Who did it? In the 1700’s a Swedish scientist founded modern taxonomy Carolus Linnaeus He created a 7 level system to classify He named this process: binomial Nomenclature He classified things by: o Shape o Structure

4. 7 Levels of Classification Kingdom Phylum Class Order Family Genus Species

5. King Philip Came Over For Good Spaghetti

6. Scientific Name Has 2-parts Usually Latin or Greek Used to group the animals and simplify the process of knowing where they belonged in the classification process Genus (1 st ): Capital Specific (2 nd ): lower case o Example: Asian Elephant o Scientific Name: Elephas maximus o Genus: Elephas o Specific: maximus

7. Scientific Names Water Buffalo  Bufo Bufo Bufo Red Wolf  Canis Lupus Rufus Canis Lupus Rufus Bottle Nosed Dolphin  Tursiops Truncatus Tursiops Truncatus

8. Humans… Humans Scientific Name: Homo sapiens

9. Dichotomous Key Dichotomous Key: an aid that is used to identify organisms and that consist of the answers to a series of questions Important to help scientist group new unknown species

10. Read steps 1a and 1b Decide which statement is true 1b is true Lets Learn How…

11. Then follow the directions after that step. Go to step 5!

12. At choice 5, you make another dichotomous choice Go to step 6! 5a is true

13. Keep going until you come to a step that gives you the creature’s name. C 6 a. The creature has one antennae Go to Step 7.

17. 6 Kingdoms 1.Plant 2.Animal 3.Archaebacteria 4.Eubacteria 5.Fungus 6.Protista

18. Plant Kingdom Plants are all multicellular and consist of complex cells. Has over 250,000 species The plant kingdom is the second largest kingdom. Plant species range from the tiny green mosses to giant trees. Without plants, life on Earth would not exist! Plants feed almost all the heterotrophs (organisms that eat other organisms) on Earth. Plants are autotrophs, organisms that make their own food

19. Animal Kingdom The animal kingdom is the largest kingdom with over 1 million known species. All animals consist of many complex cells. They are heterotrophs. Members of the animal kingdom are found in the most diverse environments in the world.

20. Archaebacteria Kingdom These are unicellular Reproduce ONLY by asexual reproduction Important because they make up many decomposers Can live in very harsh environments

21. Eubacteria Kingdom These are unicellular Reproduce ONLY by asexual reproduction These are common and you are in contact with them regularly They are the smallest organisms Make up the largest number of living things on earth

22. Fungus Kingdom Most of these are Multicellular Reproduce asexually and sexually Are important in the decomposing of dead organisms Examples: mushrooms, yeast, lichen Over 100,000 species of Fungus Do NOT ingest nutrients to live

23. Protista Kingdom Most of these are unicellular Reproduce asexually and sexually Includes more than 50,000 organisms Used in toothpaste teeth whiteners Animal like protist are called protozoans Common example: algea
