I assume you are talking about eukaryonts. They have similiar a similiar genetic code, which points to a common ancestor in the past... so they are related. In addition mitochondria or other organelles would state as evidence as well.

Is the distinction between eukaryotes and prokaryotes necessary in this context? In my opinion, it is not. 

Similarities in genetic sequence between existent eukaryotes and prokaryotes suggests that they evolved from a common prokaryotic ancestor.
