|
Prokaryotic Cell |
Eukaryotic Cell |
|
1. Size: Generally small (1-10 μm) 1 μm = 10-6m 2. The nuclear region is not well defined as the nuclear membrane is absent and is referred to as the nucleoid. 3. There is a single chromosome. 4. Membrane-bound cell organelles absent. |
1. Size: Generally large (5-100 μm) 2. Nuclear region: well-defined and girdled by a nuclear membrane. 3. There is more than one chromosome. 4. Membrane-bound cell organelles present. |
