Classification

A new organism was discovered and is found to be unicellular (single cell), contains a nucleus and organelles (ribosomes, cell wall, etc.). What domain does the organism most likely belong?

• Archaea

• Bacteria

• Eukarya

Modern classification is based on:

• similar characteristics and evolutionary history

• how they maintain homeostasis

• their geographic location (where they live)

• how they breathe and eat food

Why is the domain Eukarya separated from Bacteria and Archaea on the tree of life?

• Eukarya require energy to live, but Bacteria and Archaea do not.

• Organisms in the domain Eukarya have cells with a nucleus and membrane bound organelles, but Archaea and Bacteria are prokaryotes.

• Organisms in the domain Eukarya are made of cells that do not contain a nucleus, but Bacteria and Archaea contain a nucleus.

• All Eukarya are autotrophs, while all prokaryotes are heterotrophs.
