Begin by understanding the hierarchy of biological organization. Atoms are the smallest units of matter, forming molecules.
Molecules are combinations of atoms bonded together, but they are not considered living.
Organelles are specialized structures within cells that perform specific functions, but they are not independently living.
Cells are the smallest units of life, capable of performing all necessary functions of life independently.
Therefore, in the context of biological organization, the cell is considered the smallest living part of an organism.
