What is the Difference Between Cell and Atom?

🆚 Go to Comparative Table 🆚

The main difference between a cell and an atom lies in their composition and function. Here are the key differences between the two:

  • Composition: A cell is made of molecules, which consist of atoms. In contrast, an atom is the smallest unit of matter and is made up of subatomic particles such as protons, neutrons, and electrons.
  • Function: A cell is a fundamental membrane-bound unit of life that can be single-celled or multicellular. Cells contain macromolecules such as proteins, carbohydrates, lipids, and nucleic acids, which are essential for the functioning of living organisms. On the other hand, atoms are the basic units of chemistry and form molecules, which in turn make up cells.
  • Size: Cells are usually on the micrometer scale, while atoms are on the angstrom scale. This means that cells are larger than atoms.

In summary, cells are the smallest functional units of living organisms and are made up of molecules, which in turn consist of atoms. Atoms, on the other hand, are the smallest units of matter and form the building blocks of molecules and cells.

Comparative Table: Cell vs Atom

The main difference between a cell and an atom is that a cell is made of molecules, while atoms make up molecules. Cells are the smallest functioning units in a living organism, containing many macromolecules, while atoms are the smallest units of matter. Here is a comparison table highlighting the differences between cells and atoms:

Feature Cell Atom
Definition A cell is a biological unit and the smallest functioning unit in a living organism. An atom is a chemical unit and the smallest unit of matter.
Composition Cells contain macromolecules such as proteins, carbohydrates, lipids, and nucleic acids. Atoms are made up of subatomic particles, including electrons, protons, and neutrons.
Size Cells are usually on the micrometer scale. Atoms are on the angstrom scale, which is much smaller than the cell scale.
Living Organisms Cells are the basic structural and functional units of living organisms. Atoms are not living organisms but are the building blocks of molecules.

In summary, cells are the smallest units of life and are made up of molecules, while atoms are the smallest units of matter and make up molecules. Cells are biological units, while atoms are chemical units.
