What's the difference in prokaryotic and eukaryotic cells in its chromosomes and nucleus?

Nucleus differences:

Eukaryotes have nuclei separated from the cytoplasm by a double membrane and containing both chromosomes and a nucleolus, whereas prokaryotes have no true nucleus, with their nuclear material distributed diffusely throughout the interior of the cell.

Chromosome difference

eukaryotes is arranged into multiple chromosomes bound to the protein histone, while prokaryotes contain a single circular strand of DNA and have no histones
