A
Prokaryotic cells have multiple nuclei.
B
Prokaryotic cells have a nucleus similar to eukaryotic cells.
C
Prokaryotic cells lack a nucleus.
D
Prokaryotic cells have a well-defined nucleus.
Verified step by step guidance1
Understand the basic difference between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and do not have membrane-bound organelles, while eukaryotic cells have complex structures including a nucleus.
Recall that the nucleus is a membrane-bound organelle that contains the genetic material in eukaryotic cells. It is absent in prokaryotic cells.
Recognize that prokaryotic cells, such as bacteria and archaea, have their genetic material located in a region called the nucleoid, which is not enclosed by a membrane.
Evaluate the given statements: 'Prokaryotic cells have multiple nuclei' and 'Prokaryotic cells have a well-defined nucleus' are incorrect because prokaryotic cells do not have any nucleus.
Conclude that the statement 'Prokaryotic cells lack a nucleus' is true, as it accurately describes the absence of a nucleus in prokaryotic cells.
