Cell is the fundamental structural and functional unit of all living organisms because:
| 1. | Anything less than a complete structure of a cell does not ensure independent living. |
| 2. | The metabolic reactions can only occur inside a living cell. |
| 3. | Nucleic acids present in the cells ensure living state. |
| 4. | The membrane bound organelles cause differentiation for proper functioning. |
