I am something like a big city. I have dozens of power station, a sophisticated communications setup and a transportation system. I import raw materials, manufacture goods, operate a garbage disposal system. I have an efficient government - a rigid dictatorship, and I police my precincts to keep out undesirables. I am a cell, one of the 60 trillion in your body. The cell is often called the basic element of life. Actually we are life itself. There is no such thing as a typical cell. We are as different in form and function as a giraffe and a mouse. We come in all sizes, the largest of all being and ostrich egg. From there we scale down to a point where a million of us could sit comfortably on the head of a pin. And we come in a variety of shapes such as discs, rods and spheres.
