Answer 1

	Prokaryotic cell		Eukaryotic cell
1.	Size: generally small (1-10 µm) 1 µm = 10-6 m	1.	Size: generally large (5-100 µm)
2.	Nuclear region: poorly defined because of the absence of a nuclear membrane, and is known as nucleoid	2.	Nuclear region: well-defined and surrounded by a nuclear membrane
3.	Chromosome: single	3.	More than one chromosome
4.	Membrane-bound cell organelles absent	4.	Membrane-bound cell organelles such as mitochondria, plastids, etc., are present
