2.	Nucleus is absent (nuclear region or nucleoid is not surrounded by a nuclear membrane).	2.	Nucleus is present (nuclear material is surrounded by a nuclear membrane).
3.	It contains a single chromosome.	3.	It contains more than one chromosome.
4.	Nucleous is absent.	4.	Nucleous is present.
5.	Membrane bound cell organelles are absent.	5.	Membrane bound cell organelles such as mithochondria, plastids, endoplasmic recticulm, Golgi apparatus, lysosomes, peroxisomes, etc. are present.
6.	Cell division takes place by fission or budding (no mitosis).	6.	Cell division occures by mitotic or meiotic cell division.
