    Question

    Which of the following is the smallest structural unit?

    1. Cell    
    2. Mitochondria    
    3. Golgi body    
    4. Nucleus    

    Hint:

    Cell is the smallest structural and functional unit of life

    The correct answer is: Cell

      • Cell is the smallest structural and functional unit of life 
      • It is the smallest structure capable of independent existence 
      • All the metabolic, physiological,  genetic functions are carried inside the cells 
      • Cell organelles are incapable of independent existence .
