Classifying and Exploring Life REVIEW

Front

What is the taxonomic system?

Back

A hierarchical system used to classify and organize living organisms into categories such as domain, kingdom, phylum, class, order, family, genus, and species.

Front

What are the main kingdoms in the taxonomic classification?

Back

The main kingdoms are Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria.

Front

What is a limitation of a model in the taxonomic system?

Back

A limitation may include oversimplification, such as showing fewer kingdoms than actually exist.

Front

What is the significance of the genus in classification?

Back

The genus is a category that groups species that are closely related and share a common ancestor.

Front

How do scientists determine similarities and differences between organisms?

Back

Scientists compare characteristics such as physical traits, genetic information, and evolutionary history.

Front

What does it mean for organisms to share a common ancestor?

Back

It means that the organisms have evolved from a species that existed in the past.

Front

What is the purpose of a taxonomic key?

Back

A taxonomic key is a tool that helps identify organisms based on their characteristics.

Front

What is the role of the phylum in the taxonomic hierarchy?

Back

The phylum is a higher taxonomic category that groups together related classes of organisms.

Front

What is the difference between Archaea and Bacteria?

Back

Archaea are single-celled organisms that often live in extreme environments, while Bacteria are more common and can be found in various environments.

Front

What is an example of a characteristic used to classify organisms?

Back

Examples include cell type (prokaryotic or eukaryotic), mode of nutrition (autotrophic or heterotrophic), and habitat.
