Answer:
Ok, first you have prokaryote cells, which are simple, smaller and do not have any organelles like for example a mitochondria or vacuole. these cells are often found in unicellular organisms like bacteria and Archaea.
Eukaryote cells, on the other hand, are more complex, bigger and have different organelles (each with a specific function, in order to make the cell function properly). Organisms with eukaryote cells can be either unicellular like protists or multicellular like animals or plants.
