Verified step by step guidance

Understand the key difference between eukaryotic and prokaryotic cells: Eukaryotic cells have a membrane-bound nucleus, while prokaryotic cells do not. This is a defining feature of eukaryotes.

Analyze the first option: 'Surrounded by a plasma membrane.' Both eukaryotic and prokaryotic cells have a plasma membrane, so this feature does not distinguish them.

Analyze the second option: 'Presence of a membrane-bound nucleus.' This is a unique feature of eukaryotic cells and is absent in prokaryotic cells, making it a distinguishing characteristic.

Analyze the third option: 'Containment of genetic material.' Both eukaryotic and prokaryotic cells contain genetic material (DNA), so this feature is not exclusive to eukaryotic cells.

Analyze the fourth option: 'Ability to perform cellular respiration.' Both eukaryotic and prokaryotic cells can perform cellular respiration, though the mechanisms and structures involved may differ. Therefore, this is not a distinguishing feature.
