Prokaryotes are single-celled and eukaryotes are multicellular. Prokaryotes are bacteria and don't have a nucleus but Eukaryotes are animals and they do have a nucleus.
eukaryote cells have a membrane -bound nucleus and prokaryote cells do not. the nucleus is where eukaryote ls store their genetic information and prokaryotes have no membrane bound organelles.
Aerobic respiration uses oxygen to produce ATP. Anaerobic respiration uses inorganic molecules to produce ATP. I hope that answered your question, my friend. :)
