Question

Quizplus · Accepted Answer

Closed internal compartments, such as the nucleus and organelles, are a defining feature of eukaryotic cells and distinguish them from prokaryotes, which lack these structures. While features such as DNA, the plasma membrane, ribosomes, and heterotrophy are all present in both eukaryotes and prokaryotes, the absence of closed internal compartments is the key difference that sets them apart.
