Prokaryotic Cell:
(i) Size of the cell is generally small (1-10 m).
(ii) The nuclear region is poorly defined, due to the absence of nuclear membrane, known as a nucleoid.
(iii) It contains a single chromosome.
(iv) The nucleolus is absent.
(v) Membrane-bound cell organelles are absent.
Eukaryotic Cell:
(i) Size of the cell is generally large (50 – 100 m)
(ii) The nuclear region is well-defined and surrounded by a nuclear membrane.
(iii) It contains more than one chromosome.
(iv) The nucleolus is present.
(v) Cell organelles such as mitochondria, plastids, endoplasmic reticulum, golgi apparatus, lysosomes, peroxisomes, etc. are present
