2.	Nuclear region: ____________ ____________ and is known as _____.	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.	____________ ____________ ____________

Answer 1

Prokaryotic cell		Eukaryotic cell
1.	Size: generally small (1-10 µm) 1µ	1.	Size: generally large (5-100 µm)
2.	Nuclear region: Poorly defined due to the absence of a nuclear membrane and 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 are absent.	4.	Membrane-bound cell organelles, such as mitochondria, lysosomes, endoplasmic reticulum, Golgi complexes, etc., are present.
