Eukaryotic cells are characterized by the presence of a nucleus, which houses the cell's genetic material, and a cell membrane that encases the entire cell. This structural complexity allows eukaryotic cells to compartmentalize various cellular functions within organelles, including the endoplasmic reticulum, Golgi apparatus, mitochondria, and more.

In contrast, prokaryotic cells, which include bacteria and archaea, lack a true nucleus. Their genetic material is typically organized in a single, circular strand of DNA located in a region called the nucleoid, and while they do have a cell membrane, they do not possess the same degree of internal compartmentalization as eukaryotic cells.

Therefore, the correct answer highlights the defining features of eukaryotic cells, making them the only cell type that contains both a cell membrane and a nucleus.
