Eukaryotes and prokaryotes are two classes of organisms, based on the number of cells in the organism and the makeup of the cells. Prokaryotes generally contain only one cell, or are "unicellular." Eukaryotes, on the other hand, are organisms that contain more than one cell, or are "multicellular." Eukaryotes are very complex as compared to prokaryotes. Some examples of prokaryotes include bacteria and archaea. All the higher life forms, such as, plants, animals, human beings, etc. are examples of eukaryotic life forms. Eukaryotes contain membrane bound organelles such as mitochondria, golgi bodies, endoplasmic recticulum, etc. All such organelles are absent in prokaryotes. Eukaryotes are much bigger in size as compared to prokarytes and can be as big as a whale or a dinosaur, etc. Eukaryotes also contain a nucleus, which is absent from prokaryotes.
Hope this helps.
