The cell is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life. Cells are often called the 'building blocks of life'. The study of cells is called cell biology, cellular biology, or cytology. Cells are often called the 'building blocks of life'.

Mitochondria generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy. They are therefore called the powerhouse of the cell.
