Prokaryotes are characterized as more simple compared to eukaryotes. They do not have membrane-bound organelles or a nucleus (instead, they have a central DNA plasmid). They are also much smaller.
Eukaryotic cells have a membrane-bound nucleus, whereas prokaryotic cells do not. In eukaryotes, the nucleus is just one of numerous membrane-bound organelles. Prokaryotes, on the other hand, lack organelles that are attached to the membrane.
