Final answer:
Prokaryotic cells are found in bacteria and archaea, which differ from eukaryotic cells that make up protists, plants, and fungi because they lack a defined nucleus.
Step-by-step explanation:
The question asks which of the following consist of prokaryotic cells. Prokaryotic cells are simpler and predominantly single-celled organisms that lack a defined nucleus and organelles. The organisms that consist of these cells are classified under two domains: Bacteria and Archaea. Thus, the correct answer is d) bacteria and archaea, as both are considered prokaryotes, whereas protists, plants, and fungi are composed of eukaryotic cells, which do have a defined nucleus and organelles.
