6th - Levels of Classification

A scientist finds a seashell. She wants to classify the shell. What two different characteristics would she examine to classify the seashell?

• blood characteristics and naming characteristics

• chemical characteristics and DNA characteristics

• physical characteristics and environmental characteristics

• physical characteristics and chemical characteristics

Which of the following identifies the levels of classification in the correct order?

• domain, kingdom, phylum, class, order, family, genus, species

• genus, species, domain, kingdom, phylum, class, order, family

• domain, kingdom, genus, species, phylum, class, order, family

• genus, species, phylum, class, order, family, domain, kingdom

A branching diagram uses shared characteristics to classify organisms. On a branching diagram that compares the major kingdoms of the Domain Eukarya, what label might appear to differentiate animals form organisms in the other kingdoms?

• multicellular, move independently

• single-celled, make own food

• multicellular, make own food

• release digestive juices into surroundings

• multicellular

• undergo photosynthesis

• membrane-bound organelles

• able to tolerate extreme conditions

Felicia's teacher gives her the following list of types of organisms. 1. Fern 2. yeast 3. Algae 4. insects Felicia needs to identify the kingdom for each type of organism. In what order could she list the kingdoms for organisms 1 through 4?

• Plantae, Fungi, Protista, Animalia

• Animalia, Protista, Plantae, Fungi

• Plantae, Protista, Fungi, Animalia

• Fungi, Plantae, Protista, Animalia

During a research project, a scientist collects snails from a beach. He finds several snails that have shells of about the same size and shape. However, the shells have very different patterns and colors. How could the scientist best decide whether the snails belong to different species or to the same species?

• He could study how the snails develop

• He could examine the snails' RNA and DNA

• He could classify the snails according to shell color.

• He could look for other physical similarities in the snails.

As Carolus Linnaeus was growing up, he was interested in botany and in the names of plants. His ideas have influenced generations of biologists. How did Carolus Linnaeus contribute to modern classification systems?

• He identified the three domains of life.

• He developed two-part scientific names.

• He standardized common names of organisms.

• He used chemical characteristics to classify organisms.

The pictures show four types of organisms. Which of these would you most expect to be true if these organisms were classified by their physical characteristics only.

• organisms 1 and 3 would be in the same species

• organisms 2 and 4 would be in the same genus

• organisms 1 and 3 would be more closely related than organisms 2 and 4

• organisms 2 and 4 would be more closely related than organisms 1 and 3

What are the characteristics that define living things? What additional question would be best for Kayla to add to her list about classification.

• How are living things related?

• How do living things get energy?

• What do living things need to survive?

• Where do living things make their home?
