      Why is cell called the structural and functional unit of life?      [NCERT]

    Answer:

                      All living organisms are made up of cells. This shows that the cell is structural unit of life. Each living cell has the capacity to perform certain basic functions that are characteristics of all living forms. For example, phagocytic cells eat or kill unwanted or foreign particles inside the body (e.g., WBCs), some cells, e.g., pancreatic cells, small intestine cells, liver cells secrete enzymes and hormone. Each cell has its own individual function. Therefore, cell is called the structural and functional unit of life.
