• D. Nucleus

Answer: (D)

Verified step by step guidance

1. Understand the basic difference between eukaryotic and prokaryotic cells: Eukaryotic cells have a defined nucleus, while prokaryotic cells do not.
2. Identify the structures listed in the problem: Ribosomes, Cell wall, Plasma membrane, and Nucleus.
3. Recall that ribosomes are present in both eukaryotic and prokaryotic cells, as they are essential for protein synthesis.
4. Recognize that a cell wall can be found in both types of cells, although its composition may differ (e.g., peptidoglycan in prokaryotes and cellulose in plant eukaryotes).
5. Note that the plasma membrane is a common feature of all cells, serving as a barrier and regulating the movement of substances in and out of the cell. The nucleus, however, is unique to eukaryotic cells, housing the cell's genetic material.
