A prokaryote cell has no distinct nucleus with a membrane and neither does it have other specialized organelle.
In a eukaryotic cell, the genetic material is DNA in the form of chromosomes which are found within a distinct nucleus.

Examples of Eukaryotes include protozoa such as amoeba, fungi, plants, animals and generally all multicellular organisms.
