Prokaryotic cell	Eukaryotic cell
The nucleus is not well defined and is called the nucleoid.	The nuclear region well-defined nucleus with a nuclear membrane.
A single length of only deoxyribonucleic acid (DNA)	Several lengths of genetic material (chromosomes) containing DNA are wound around certain proteins.
Small ribosomes	Larger ribosomes
No other cell organelles	Several organelles like mitochondria, endoplasmic reticulum, chloroplasts, etc
Examples: Bacteria, Blue-green algae (Cyanobacteria)	Examples: Euglena, Amoeba, and all plants and animals
