Three Domains of Life

What are the three domains of life in the classification of living things?

• Animalia, Plantae, Fungi

• Bacteria, Archaea, Eukarya

• Protista, Monera, Fungi

• Eukaryota, Prokaryota, Archaea

Which domain do humans belong to?

• Bacteria

• Archaea

• Eukarya

• Protista

Explain why viruses are not classified within the three domains of life.

• They are too small to be classified.

• They do not have a cellular structure.

• They can reproduce on their own.

• They are only found in water.

Identify the domain that includes organisms with a nucleus.

• Bacteria

• Archaea

• Eukarya

• Monera

Compare the cell structure of organisms in the domains Bacteria and Archaea.

• Both have a nucleus.

• Both lack a nucleus but have different cell wall compositions.

• Bacteria have a nucleus, Archaea do not.

• Archaea have a nucleus, Bacteria do not.

Predict how the classification of living things might change with the discovery of new organisms.

• The number of domains will decrease.

• New domains may be added to accommodate unique life forms.
