What is the difference between prokaryotic and eukaryotic cells?

The main difference that separates prokariotic organisms from eukaryotic organisms is the organisation of the genetic material. Prokaryotes have a single chromosome that isn't separated by a membrane and it's called nucleoid. Eukaryotes have multiple chromosomes that are inclosed in a nuclear envelope(nucleus).

The only organelles present in prokaryotic cells are the ribosomes(70S) which differ from the eukaryotic ribosomes(80S). Eukaryotic cells have membrane bound organelles like the mitochondrion or Golgi aparatus.
