A
Both prokaryotic and eukaryotic cells
B
Prokaryotic cell
C
Neither prokaryotic nor eukaryotic cells
D
Eukaryotic cell
Verified step by step guidance
1
Understand the difference between prokaryotic and eukaryotic cells: Prokaryotic cells lack a membrane-bound nucleus, while eukaryotic cells have a membrane-bound nucleus that houses their genetic material.
Recall that prokaryotic cells, such as bacteria and archaea, have their DNA located in a region called the nucleoid, which is not enclosed by a membrane.
Eukaryotic cells, such as those found in plants, animals, fungi, and protists, have a well-defined nucleus enclosed by a nuclear membrane, which separates the genetic material from the cytoplasm.
Eliminate the incorrect options: 'Prokaryotic cell' is incorrect because these cells do not have a membrane-bound nucleus. 'Both prokaryotic and eukaryotic cells' is incorrect because only eukaryotic cells have this feature. 'Neither prokaryotic nor eukaryotic cells' is also incorrect because eukaryotic cells do have a membrane-bound nucleus.
Conclude that the correct answer is 'Eukaryotic cell,' as it is the only type of cell that contains a membrane-bound nucleus.
