Biology Benchmark 3 Review

Scientists discover a single-celled organism in pond water that has a nucleus. This organism can move using a flagellum (flagella). Which pair of words can be used to describe this organism?

• Prokaryotic and unicellular

• Prokaryotic and motile

• Eukaryotic and multicellular

• Eukaryotic and motile

Characteristics of an organism:
1. Cannot move itself around
2. Absorbs food particles
3. Made of many cells
4. Cells have nuclei
Which word cannot be used to describe this organism?

• Eukaryotic
• Heterotrophic
• Immotile
• Unicellular

Scientists are studying an organism that can make its own food. It is made of trillions of cells, and each cell has its own nucleus. Which pair of words could be used to describe this organism?

• Autotrophic and prokaryotic
• Autotrophic and eukaryotic
• Heterotrophic and eukaryotic
• Heterotrophic and multicellular

Animals are considered highly motile organisms. This is because animals-

• can make their own food
• can move themselves around
• are composed of a single cell
• do not contain nuclei in their cells

Which of the following kingdoms are matched correctly with their domain?

• Archaea --> Bacteria, Protists, Fungi

• Eukayra --> Bacteria, Protists & Fungi

• Eukarya --> Plantae, Animalia & Fungi

• Bacteria --> Archaea, Animalia, Protists

Which animal would be classified in the Kingdom Animalia?

• Organism 1

• Organism 2

• Organism 3

• Organism 4

Protists are a group of mostly single-celled organisms. All protists are considered eukaryotic. What makes protists eukaryotic?

• All protists can make their own food
• All protists contain a cell nucleus
• Every protist is able to move itself around
• Every protist is classifies as unicellular

This domain is characterized by ancient bacteria that can live in extreme environments, such as volcanoes.

• Archaea
• Bacteria
• Eukarya
• Prokarya

Organisms in the Kingdom Animalia are mostly unicellular Eukaryotes.

• True
• False

What are the three domains?

• Archaea, Bacteria, and Eubacteria
• Archaea, Protists, and Eubacteria
• Archaea, Bacteria, and Eukarya
• Archaea, Fungi, Animalia
