Begin by understanding the basic differences between eukaryotic and prokaryotic cells. Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.
Identify the structures listed in the problem: Nucleus, Cytoplasm, Cell membrane, and Ribosome.
Recall that the nucleus is a membrane-bound organelle that houses the cell's genetic material and is a defining feature of eukaryotic cells.
Consider the other structures: Cytoplasm, Cell membrane, and Ribosome. These are found in both eukaryotic and prokaryotic cells.
Conclude that the nucleus is the structure present only in eukaryotic cells, as it is not found in prokaryotic cells.
