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.
