Eukarya have which kind of cell type?

• A. Prokaryotic
• B. Eukaryotic
• C. Both
• D. None

Answer: (B)

The main idea here is that organisms in the Eukarya domain have cells with a defined nucleus and internal, membrane-bound organelles, i.e., eukaryotic cells. This structure includes organisms like animals, plants, fungi, and many protists, all sharing a nucleus that houses their DNA and an internal membrane system that organizes cellular processes.

That contrasts with prokaryotic cells found in bacteria and archaea, which lack a true nucleus and membrane-bound organelles and tend to have a simpler organization. Because Eukarya are defined by having eukaryotic cells, the correct answer is that they have eukaryotic cells.

The other descriptions don’t fit: prokaryotic would describe the other two domains of life, both would incorrectly imply Eukarya have two cell types, and none would be wrong since there is a correct characterization.
