Ribosomes are non-membrane bound organelles found in:
| 1. | All prokaryotic cells only | 
| 2. | All eukaryotic cells only | 
| 3. | All somatic cells in eukaryotic organisms only | 
| 4. | All cells | 
| I: | independent existence | 
| II: | performing the essential functions of life | 
| I. | All living organisms are composed of cells. | 
| II. | The cell is the basic unit of life. | 
| III. | All cells come from pre-existing cells through sexual reproduction. |
