Detailed explanation-1: -Cells Unit. Cells are basic units of structure and function in living things. This means that cells form the parts or an organism and carry out all of the an organism’s processes, or functions.

Detailed explanation-2: -Cells are structural units as they form the structure of the organism. Cells combine to form tissues, which further combine to form organs, and organs combine to form organic systems, which further combine to form an organism. So, the cell is the basic structural unit for all unicellular and multicellular organisms.

Detailed explanation-3: -Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane-which, much like the walls of a house, serves as a clear boundary between the cell’s internal and external environments.
