Which feature is found in prokaryotic cells but not in eukaryotic cells?

a. cytoplasm

b. nucleoid

c. plasma membrane

d. nucleus

The correct answer is B - nucleoid.

The nucleoid is a region in a prokaryotic cell that houses the main DNA material of the cell.

In contrast to eukaryotic cells with a nucleus, prokaryote have a nucleoid where the genetic material can be found. The nucleoid is different from the nucleus in eukaryotes in that the genetic material is not enclosed in a membrane to separate it from the cytoplasm.

The nucleoid usually contains only a single chromosome which has the cell DNA.
