Difference between prokaryotic and eukaryotic cells

Prokaryotic cell	Eukaryotic cell
§  An organized nucleus is absent.	§  A well organized nucleus is found.  It is differentiated into nuclear envelope, chromatin network, nucleolus and nucleoplasm.
§  DNA is naked i.e., without an association with histones.	§  Nuclear DNA is associated with histone proteins.
§  DNA is usually circular.	§  Nuclear DNA is linear but extra nuclear DNA is usually circular.
§  A prokaryotic cell has one envelope organization.	§  An eukaryotic cell has two envelope organization.
§  ER, mitochondria, GC, centrioles, lysosomes, sap vacuole and other cell organelles are absent.	§  These are present.
§  Ribosomes are of 70S type.	§  Ribosomes are of 80S, but 70S type of ribosomes occur in plastids & mitochondria
§  Cytoplasm does not show streaming movements.	§  Cytoplasm usually shows streaming movement.
§  Spindle apparatus is not formed during division.	§  A spindle apparatus is produced during nuclear division.
