PROKARYOTIC Vs EUKARYOTIC CELL

	Eukaryotic Cell	Prokaryotic Cell
Nucleus:	Present	Absent
Number of chromosomes:	More than one	One--but not true chromosome: Plasmids
Cell Type:	Usually multicellular	Usually unicellular (some cyanobacteria may be multicellular)
True Membrane bound Nucleus:	Present	Absent
Example:	Animals and Plants	Bacteria and Archaea
Genetic Recombination:	Meiosis and fusion of gametes	Partial, undirectional transfers DNA
Lysosomes and peroxisomes:	Present	Absent
Microtubules:	Present	Absent or rare
Endoplasmic reticulum:	Present	Absent
Mitochondria:	Present	Absent
Cytoskeleton:	Present	May be absent
DNA wrapping on proteins.:	Eukaryotes wrap their DNA around proteins called histones.	Multiple proteins act together to fold and condense prokaryotic DNA. Folded DNA is then organized into a variety of conformations that are supercoiled and wound around tetramers of the HU protein.
Ribosomes:	larger	smaller
Golgi apparatus:	Present	Absent
Chloroplasts:	Present (in plants)	Absent; chlorophyll scattered in the cytoplasm
Flagella:	Microscopic in size; membrane bound; usually arranged as nine doublets surrounding two singlets	Submicroscopic in size, composed of only one fiber
Permeability of Nuclear Membrane:	Selective	not present
Plasma membrane with steroid:	Yes	Usually no
Cell wall:	Only in plant cells and fungi (chemically simpler)	Usually chemically complexed
Cell size:	10-100um	1-10um
