Multiple Choice
Which type of cells lack a membrane-bound nucleus?
A
Prokaryotic cells (e.g., bacteria and archaea)
B
Eukaryotic cells (e.g., plants, animals, fungi, and protists)
C
Only plant cells
D
Only animal cells
Verified step by step guidance1
Understand the difference between prokaryotic and eukaryotic cells: Prokaryotic cells do not have a membrane-bound nucleus, while eukaryotic cells do.
Recall that prokaryotic cells include organisms such as bacteria and archaea, which have their genetic material freely located in the cytoplasm.
Recognize that eukaryotic cells, including plant, animal, fungal, and protist cells, have their DNA enclosed within a distinct nucleus surrounded by a nuclear membrane.
Eliminate options that specify only plant or only animal cells, since both are eukaryotic and have membrane-bound nuclei.
Conclude that the correct answer is prokaryotic cells, as they lack a membrane-bound nucleus.
