Cells are made up of molecules. Why then do we say that the structural unit of a living thing is a cell and not a molecule?

Molecule is a non- living structure, but they are responsible for assembling in various ways to create the parts of cells.

Explanation:

Molecules cannot function independently whereas when they combine they give rise to a functional unit called cell. This is the reason why cell is called a functional unit of life and not molecules.
