So eukaryotes have nuclei, but the thing that makes them special is the mitochondria. Do we see anything that has a nucleus but not mitochondria, or vice versa?
We know of at least one eukaryote species that lost its mitochondria. I don’t know about mitochondria but no nucleus. Erythrocytes don’t have either, so maybe (speculating here) there are some specialized animal cells that have mitochondria but no nuclei.
