How is a prokaryotic cell different from a eukaryotic cell?

1.	How is a prokaryotic cell different from a eukaryotic cell?
Answer» 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
