(N/A) The cell is considered the structural unit of life because all living organisms are composed of cells,which provide the basic framework and organization for the body.
It is called the functional unit of life because all metabolic activities and physiological processes necessary for survival,such as respiration,protein synthesis,and waste excretion,occur within the cell.
These activities are carried out by specialized structures known as cell organelles,which perform specific tasks like energy production,transportation,and synthesis of materials.
Therefore,the cell is the smallest unit capable of performing all life processes independently.
