Answer:

The main difference between eukaryotic and prokaryotic cells is the nucleus. In eukaryotic cells, the nucleus is surrounded by a membrane that separates the nucleus from the cytoplasm and other organelles. In prokaryotic cells, the nucleus is not surrounded by a membrane. Instead, the DNA is located in the nucleoid region in the cytoplasm.
