Which type of cells possess a cell membrane?

Prokaryotic cells, which lack a true nucleus and membrane-bound organelles, do indeed possess a cell membrane. However, stating that only prokaryotic cells have a cell membrane excludes eukaryotic cells, which also have cell membranes. Therefore, this choice is incorrect as it does not recognize the presence of cell membranes in both cell types.

Eukaryotic cells are characterized by having a defined nucleus and membrane-bound organelles, and they possess cell membranes. However, this choice is incorrect because it overlooks the fact that prokaryotic cells, such as bacteria, also contain cell membranes. Thus, eukaryotic cells alone do not represent the complete picture.

This option is incorrect because both prokaryotic and eukaryotic cells possess cell membranes. Claiming that none of the choices are correct fails to recognize the fundamental characteristic shared by all cells in terms of membrane structure.
