Prokaryotes
Prokaryotes are a group of organisms that lack a cell nucleus, or any other membrane-bound organelles.
Prokaryotic cells are generally much smaller and more simple than eukaryotic. Prokaryotic cells are, in fact, able to be structurally more simple because of their small size
Eukaryotes
The cells of “complex” organisms, including all plants and animals
Can specialize for certain functions
Contain a nucleus and many other organelles, each surrounded by a membrane (the nucleus and mitochondrion have two membranes)
Plant and animal (eukaryotic) cells are different

It contains most of the cell's genetic material
It organizes work of the cell
