Multiple Choice
Which type of cell lacks a membrane-bound nucleus?
A
A prokaryotic cell (e.g., a bacterium)
B
A eukaryotic plant cell
C
A eukaryotic fungal cell
D
A eukaryotic animal cell
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 like bacteria and archaea, which have their genetic material free-floating in the cytoplasm.
Recognize that eukaryotic cells, such as plant, fungal, and animal cells, have a defined nucleus enclosed by a nuclear membrane.
Identify that the question asks for the type of cell lacking a membrane-bound nucleus, which points to prokaryotic cells.
Conclude that the correct answer is a prokaryotic cell (e.g., a bacterium) because it lacks a membrane-bound nucleus.
