Question

Cell is the fundamental structural and functional unit of all living organisms. This was evidenced by the fact that:

• A. All cells arise by the fusion of two cells
• B. All cells are totipotent
• C. Subcellular components can regenerate a complete cell
• D. Anything less than a complete structure of a cell does not ensure independent living

Answer 1

The correct option is D Anything less than a complete structure of a cell does not ensure independent living

Unicellular organisms are capable of (i) independent existence, (ii) performing the essential functions of life. Anything less than a complete structure of a cell do not ensure independent living. Hence, cell is the fundamental structural and functional unit of all living organisms.
