By definition, a prokaryote is a single celled organism. An onion is made up of many cells, hence, it is a eukaryote.
You know a cell is an organism by telling if it is a prokaryote or an eukaryote. A prokaryote has no nucleus (brain), and an eukaryote does.
An onion cell is a plant cell, thereby it is eukaryotic. Prokaryotic cells are only found by bacterias.
You will find nucleic acid in both prokaryote and eukaryote cells.
