Difference between Prokaryotic and Eukaryotic Cells

The Major Difference between Prokaryotic and Eukaryotic Cells is that Prokaryotic cells have no membrane-bound nucleus and organelles, cell size ranges from 0.5um to 100um While Eukaryotic Cells have a membrane-bounded nucleus, cell size ranges from 10um to 150um.

Prokaryotic Cells	Eukaryotic Cells
1.Prokaryotic cells do not have well defined nucleus. They do not have nuclear membrane. The nuclear material (DNA) is directly submerged in cytoplasm.	1.Eukaryotic cells do not have well defined nucleus. They have nuclear membrane.
2. The organism possessing prokaryotic cells are called prokaryotes.	2. The organism possessing eukaryotic cells are called eukaryotes.
3. Prokaryotes lack membranous bound organelles. For example, mitochondria, Golgi bodies, Endoplasmic reticulum and Chloroplast are absent in prokaryotes.	3.They contain all membranous bound organelles.
4.Prokaryotes have small ribosome of 70S.	4.They have large ribosomes of 80S.
5. In prokaryotes, mitosis is absent and cell divides by binary fission. Prokaryotes are primitive organisms.	5. Their cells are divided by mitosis. The eukaryotes are advanced organisms.
6. The cell wall of the prokaryotes is made up of peptidoglycan or murein. In this case, polysaccharide chain is bound with the short chain of amino acids.	6. Only plants have cell walls. The cell wall of plants is composed of cellulose.
7. Examples: Bacteria and Blue-Green Algae (cyanobacteria)	7. Examples: all other animals and plants, fungi and Protista.
