Answer:
Cell membranes, DNA, ribosomes and cytoplasm.
Explanation:
Prokaryotic cells are cells without a nucleus and membrane bound organelles.
Eukaryotic cells are cells with a nucleus and membrane bound organelles, like mitchondria or endoplasmic reticulum.
Both have cell membranes that surround the cell. Both have DNA. In prokayotic the DNA is in a part of the cell called a nucleoid. In eurkaryotic, it is held in the nucleus. Both have ribosomes that make proteins, however prokaryotic cells have fewer. Both have cytoplasm as well.
Therefore, both prokaryotic and eukaryotic cells have cell membranes, DNA, ribosomes and cytoplasm.
