Eukaryotic cells have a membrane-bound nucleus; prokaryotic cells do not.

Prokaryotic cells have a cell membrane; eukaryotic cells have a cell wall.

Answer 1

The statement that describes the major difference between prokaryotic and eukaryotic cells is:

Eukaryotic cells have a membrane-bound nucleus; prokaryotic cells do not.

This is a fundamental distinction between the two types of cells, as prokaryotic cells (like bacteria) lack a true nucleus and other membrane-bound organelles, while eukaryotic cells (like those in plants, animals, fungi, and protists) have a defined nucleus and organelles.
