Question

How is a prokaryotic cell different from a eukaryotic cell?

Answer 1

	Prokaryotic Cell	Eukaryotic cell
1.	Most prokaryotic cells are unicellular.	Most eukaryotic cells are multicellular.
2.	The cell size is generally small (0.5-5 µm).	The cell size is generally large (50-100 µm).
3.	The nuclear region is poorly defined due to the absence of a nuclear membrane, or the cell lacks a true nucleus.	The nuclear region is well-defined and surrounded by a nuclear membrane, or the true nucleus bound by a nuclear membrane is present in the cell.
4.	It contains a single chromosome.	It contains more than one chromosome.
5.	The nucleolus is absent.	Nucleolus is present.
6.	Membrane-bound cell organelles such as plastids, mitochondria, endoplasmic reticulum, Golgi apparatus, etc. are absent.	Cell organelles such as mitochondria, plastids, endoplasmic reticulum, Golgi apparatus, lysosomes, etc. are present.
7.	Cell division occurs only by mitosis.	Cell division occurs by mitosis and meiosis.
8.	Prokaryotic cells are found in bacteria and blue-green algae.	Eukaryotic cells are found in fungi, plants, and animal cells.
