Here's a summary of the differences between prokaryotic and eukaryotic cells based on the provided features:

Prokaryotic cells, such as bacteria, are characterized by the absence of a true nucleus and nuclear membrane, with their genetic material (mainly circular DNA and plasmids) freely located in the cytoplasm. They also lack membrane-bound organelles and possess 70S ribosomes. In contrast, eukaryotic cells, found in plants, animals, and fungi, have a true nucleus enclosed by a nuclear membrane, containing linear DNA and generally no plasmids. They feature various membrane-bound organelles and 80S ribosomes, with cell walls made of cellulose or chitin if present.
