Answer

The cell is called the structural and functional unit of life because it serves as both the basic building block and the smallest living component capable of independent function. Structurally, all living organisms are made up of cells, either single or multiple cells organized into tissues and organs. Functionally, cells carry out all essential life processes including nutrition, respiration, growth, reproduction, and waste elimination. Even in multicellular organisms, each cell maintains its own vital functions while contributing to the organism's overall survival.
