What is one defining characteristic of a prokaryotic cell?

A. ribosomes make protein

B. organelles have no membranes

C. cell contains DNA

D. cytoplasm fills cell

B. organelles have no membranes

Explanation:

Unlike eukaryotic cells, prokaryotic cells lack organelles with membranes.

So, prokaryotic cells are found in unicellular organisms with a single chromosome that have no nuclear envelope and no membrane-bound organelles i.e organelles like mitochondria, golgi bodies etc all lack membrane.

Examples of prokaryotic cells are bacteria and cyanobacteria
