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


A cell is defined as the smallest, basic unit of life that is responsible for all of lifeโ€™s processes. Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.
