Eukaryotes comprise animals, plants, and fungi—which are mostly multicellular - as well as various other groups that are collectively classified as protists. In contrast, prokaryotes are organisms, such as bacteria and archaea, that lack nuclei and other complex cell structures.
Eukaryotes share a common origin, and are often treated formally as a superkingdom, empire, or domain. In the domain system, eukaryotes have more in common with archaean prokaryotes than bacterial prokaryotes.

Prokaryotic cells are unicellular organisms that lack organelles or other internal membrane-bound structures . Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

Advantages that Eukaryotic cells have over Prokaryotic cells

# data[].attributes.body
Prokaryotic cells have all of their DNA floating about in the cell. This is highly inefficient, and also very unorganized. Eukaryotic cells have their DNA compiled within a nucleus, which is very space efficient, since they can store thousands of times more chromosomes.

Prokaryotes are named for their lack of a membrane-bound nucleus, but prokaryotes also lack any other membrane-bound organelles. They lack any chloroplasts, mitochondria or vacuoles, and perform any functions of these organelles in their cytoplasm. Prokaryotes possess two types of genetic information storage. The first, analogous to the eukaryotic nucleus, is a cluster of chromosomes known as the nucleoid. The second, only possessed by some organisms, is the plasmid, tiny rings of additional genetic information.
