The correct answer is cells can do more in less time.
Explanation:
Human body has developed specialized cell so that specific cells can carry out specific functions of the complex human body system.
Each body cells are specialized for their specific function for example heart cells act as pump,lung cells helps in gas exchange,blood cells helps in transport of biomolecules,muscle cells helps in the contraction and relaxation.
Thus the numerous functions of human body are divided among specific cell so that each cell will have low work load and can carry out their specific functions in less time.
