<u>The structural differences between prokaryotes and eukaryotes:</u>
The main differences between the prokaryotes and eukaryotes are the presence of nucleus in the eukaryotic cells and its absence of nuleus in prokaryotes.
Also, prokaryotes are single-celled, so that a cell is a whole organism. On the other hand, eukaryotes are mostly multi cellular, and therefore more complex. More complex DNA is in the nucleus in eukaryotic cells, that allow them to carry out a wide range of functions. Prokaryotes, as a single cell, have the features of simple present.
