Why cell is known as structural unit of life

The cell is called the structural and functional unit of life as all living organisms are made up of cells. Cells are also essential for performing various life processes required for sustaining life. Furthermore, cells provide form and structure, process nutrients and convert it into usable energy.

A cell is known as a structural unit of life because it is part of what makes you. With out cells you wouldn't actually exist. They also make up animals, reptiles, mammals, fish, amphibians and any other kind of living animal like those. They are living organisms that keep you alive and in general make your existence.
