Define cell and atom​

cell is made of molecules whereas atoms make up molecules. Cells are the smallest functioning unit in a living organism

a cell is the basic structural, functional, and biological unit of all known organisms.

an atom is the smallest unit into which matter can be divided without the release of electrically charged particles
