Question

any one help me in chaapter 5 fundamental unit of life ​

Answer 1

The fundamental unit of life is cell.

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

Cells form the structure of an entity. A group of cells form a tissue, further an organ and ultimately an organ system. They perform fundamental functions and life processes such as respiration, digestion, excretion etc in both unicellular and multicellular entities. They perform all the activities independently. Hence, cells are referred to as structural and fundamental units of life.
