DO: Today we will learn about the seven classification groups. 1/22/15 Agenda: Bell work Classification of Living things Materials: - Pencil Notebook Classification Packet DO: Today we will learn about the seven classification groups. DQ: Why do we have a classification system?

KINGDOM PHYLUM CLASS ORDER FAMILY GENUS SPECIES

Definitions – Part B 1. Kingdom – the largest taxonomic group; has the largest variety of organisms 2. Phyla: more than one phylum 3. Genus: second smallest taxonomic group; made up of related species groups 4. Species: smallest and most specific taxonomic group b) only one kind of organism belongs to a species group c) members are not identical to each other (allows for individual differences) d) a group of organisms that can make offspring that are capable of reproducing

Scientific Naming System for Organisms Binomial Nomenclature Definitions: common name: name that is commonly used to identify an organism Examples: house cat, lion, gray wolf, pet dog, coyote, leopard frog

Binomial Nomenclature B) Reasons a Scientific Naming System was Needed: 1) Language differences make it difficult for scientists to communicate with each other. 2) Some organisms have more than one common name. 3) Some common names are misleading. Examples: Silverfish are insects, not fish. A seahorse is not a horse.

Binomial Nomenclature C. Carolus Linnaeus 1. Swedish scientist who lived in the 1700’s 2. He designed the scientific naming system for organisms.

Today’s scientific naming system for organisms 1. Language used was Latin because it was used by educated people. 2. Binomial nomenclature: a two-word naming system for organisms a. First word: (begins with a capital letter): This is the name of the genus group to which the organism belongs. b. Second word: (all lower case letters): This is the name of the species group to which the organism belongs. c. Scientific names are either underlined or written in italics.

Today’s scientific naming system for organisms Examples of scientific names of organisms Common Name Scientific Name Leopard Frog Rana Pipiens house cat Felis domesticus lion Panthera leo gray wolf Canis lupus pet dog Canis familiaris coyote Canis latrans human Homo sapien

Creating Scientific Names Latin endings for scientific names is us male endings ius a ia female endings onia um ium neutral endings

Creating Scientific Names Examples: Felis domesticus Ursus horribilis For Personal Names: 1st word 2nd word NOUN 1. ADJECTIVE 1st letter is a capital 2. all lower case letters Latin ending 3. Latin ending UNDERLINE 4. UNDERLINE Example #1: Froggius hoppius Example #2: Karena skatera Try making up your own name!!!

Classification Wrap-up Plants move by wind, water, or external forces (animals (Humans) Kingdom – classifies on basis of cellular organization & methods of nutrition – ingest, absorb or produce Phylum – classified on similarities in basic body plan or organization. 33 phyla. (Arthropod – (external skeleton), Mollusca – (soft, segmented body), Chordates- (Notochord-have a backbone - vertebrates), etc.

Classification So, here’s how the classification system works: Kingdom – ANIMAL or ANIMALIA Phylum – CHORDATA Class – MAMMALIA – has a backbone and nurses their young Order – RODENTIA – has a backbone, nurses their young, long sharp front teeth Family – SECURIDAE – has a backbone, nurses their young, has long sharp front teeth, and has a bushy tail Genus – TAMIASCIURUS – has a backbone, nurses their young, has long sharp front teeth, has a bushy tail and climbs trees Species – hudsonicus – brown fur on its back, white fur on its under parts Tamiasciurus hudsonicus – brown squirrel
