Cell vs. Atom: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 19, 2023
A cell is the basic unit of life in organisms, while an atom is the smallest unit of a chemical element, fundamental in physics and chemistry.

Key Differences

A cell is the fundamental structural and functional unit of all living organisms, capable of self-replication. An atom, on the other hand, is the smallest unit of a chemical element, retaining its chemical properties.
