Which is one of the most important differences between prokaryotes and eukaryotes? . a. the cytoplasm in eukaryotes does not contain any organelles but that prokaryotes does. b. eukaryotes are much smaller than prokaryotes. c. prokaryotes do not have a well defined nucleus, but eukaryotes do.

The correct answer is C.prokaryotes do not have a well defined nucleus, but eukaryotes do.

Explanation:

Prokaryotes are the organism that does not contain a true nucleus that means a membrane-bound nucleus is absent in prokaryotes but in eukaryotes, membrane-bound and well defined nucleus is present which contains the genetic material of eukaryotic cell.

As prokaryotic cell does not contain any well-defined nucleus the genetic material of prokaryotes are present in the cytoplasm of the cell and the process of transcription and translation takes place simultaneously because there no nucleus to divide these process.  Therefore the correct answer is C.

prism b but im not for sure
