Final answer:
Prokaryotic and eukaryotic cells share similarities such as containing nucleic acids and ribosomes. The main difference is that eukaryotic cells have a nucleus.
Step-by-step explanation:
Prokaryotic and eukaryotic cells are different, but they do share a few similarities. One similarity is that both cell types contain nucleic acids, which is the genetic material of the cell. Another similarity is that eukaryotic and prokaryotic cells both contain ribosomes, where protein synthesis takes place. The main difference is that eukaryotic cells are the only ones that contain a nucleus, a structure that stores the DNA and is surrounded by a complex nuclear membrane.
