5) Answer:

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 are absent 4. Membrane-bound cell organelles such as mitochondria, plastids, etc., are present.
