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

• These one-celled organisms live in harsh environments, such as the deep ocean and hot springs.

• The organisms have cell walls, reproduce by cell division, and live and on the human body.

• These unicellular organisms lack a nucleus in their cells and are found in almost any environment.
