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

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 The science of classification Aristotle 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 characteristi cs they will have in common

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

15. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Ursidae Genus: Ailuropoda Species: melanoleuca Ailuropoda melanoleuca Kingdom Animalia Phylum Chordata Class Mammalia Order Cetacea Family Delphinidae Genus Tursiops Species 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.
