(6th) Chapter 4 Lesson 2: Classifying Life

​pg. 123

​

**** Biologists use classification to organize living things into groups so that the organisms are easier to study. ​

​

​

​

Binomial = two names​

​

​

Plural form = genera​

​

The second word in an organism's scientific name often describes a distinctive feature of an organism (where it lives or its appearance). ​

pg. 126

​

*** A domain is the broadest level of organization. Within a domain, there are kingdoms. Within kingdoms, there are phylum. Within phlum are classes. Within classes are orders. Within orders are families. Each family contains one or more genera. Finally, each genus contains one or more species.

​

The more classification levels two organisms share, the more characteristics they have in common and the more closely related they are.​

pg. 128

​

*** Taxonomic keys are useful tools that help determine the identity of organisms.

• ​Domain- broadest level of organization

• Kingdom

• Phylum

• Class

• Order

• Family

• Genus

• Species​

​

​

​

• ​The more classification levels two organisms share, the more characteristics they have in common and the more closely related they are.​

• As you move down these levels of classification, the number or organisms decreases. The organisms that remain share more characteristics with one another and are more related. ​

On a separate sheet of paper write down your answers .​

​

​

​
