Unicellular- Consisting of one cellMulticellular- Consisting of many cellsProkaryote- an organism with only one cell and no nucleusEukaryote- an organism with cells and a nucleus enclosed in a membrane
Cell- The smallest unit of life!!!Heterotroph (consumer)- an organism that eats producers or other organisms for energyProducer (autotroph)- an organism that makes its own food through photosynthesis
Nucleus- The “brain” of the
cell
• Heterotroph- Organisms that consume food (consumer)

Classification • the grouping of things
according to similar characteristics
Classify putting things into
groups or categories
Why do we use classification systems?
• Gives order to the world• Easily understood and communicated
Taxonomy The science of classification
Aristotledeveloped 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
Modern Classification System 7 major groups/levels
Kingdom---- (Largest most general)
PhylumClassOrderFamilyGenusSpecies---- (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
Organisms Grouped together based on similarities in form, structure, genetics, etc
The more levels organisms share, the more characteristics they will have in common
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
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
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.
