Unicellular - Consisting of one cell Multicellular - Consisting of many cells

1. Unicellular- Consisting of one cell Multicellular- Consisting of many cells Prokaryote- an organism with only one cell and no nucleus Eukaryote- an organism with cells and a nucleus enclosed in a membrane

2. Cell- The smallest unit of life!!! Heterotroph (consumer)- an organism that eats producers or other organisms for energy Producer (autotroph)- an organism that makes its own food through photosynthesis Nucleus- The “brain” of the cell

3. Heterotroph- Organisms that consume food (consumer) • Autotroph- Organisms that make their own food through photosynthesis (producer) • Unicellular- Consisting of one cell • Multicellular- Consisting of many cells • Nucleus- The “brain” of the cell • Prokaryote- an organism with only one cell and no nucleus • Eukaryote- an organism with cells and a nucleus enclosed in a membrane • Cell- The smallest unit of life!!!

8. Classification • the grouping of things according to similar characteristics Classify putting things into groups or categories

9. Why do we use classification systems? •  Gives order to the world • Easily understood and communicated

10. Taxonomy Aristotle The science of classification • developed one of the first classification systems •   TWO MAIN CATEGORIES: • Plants • Animals • Water-dwellers… animals that swim •      Land-dwellers…. animals that walk/run • Air-Dwellers… animals that fly

11. Carolus Linnaeus developed the modern classification system

12. Modern Classification System   7 major groups/levels Kingdom---- (Largest most general) Phylum Class Order Family Genus Species---- (Smallest most Specific) • Organisms Grouped together based on similarities in form, structure, genetics, etc. •  The more levels organisms share, the more characteristics they will have in common

13. Organisms Grouped together based on similarities in form, structure, genetics, etc The more levels organisms share, the more characteristics they will have in common

14. Binomial Nomenclature • Naming method consisting of two words • Genus and Species • Genus must be capitalized • Species is lower case • All must be underlined or italicized • Ex. Homo sapiens

15. Kingdom: AnimaliaPhylum: ChordataClass: Mammalia Order: CarnivoraFamily: UrsidaeGenus: AiluropodaSpecies: melanoleuca Ailuropodamelanoleuca Kingdom AnimaliaPhylum ChordataClass Mammalia Order CetaceaFamily DelphinidaeGenus TursiopsSpecies truncates Tursiops truncates

17. 7 Levels of Classification Mnemonic Device • You can remember the correct classification sequence from the largest (most general) to the smallest (most specific) group. Just remember the following sentence: • “Kings Play Cards On Fat Green Stools” • The first letter of each word is the same as the first letter of each classification level. • Assignment: • in your field guide, create a color illustration of the mnemonic you think would be the most helpful and interesting to remember. The illustration: • (1) must be neat and colorful • (2) must take up a whole page • (3) must include the mnemonic phrase in large, neat print for a title.
