Answer:
Cells are living, and atoms are not. Matter is any substance that has mass and takes up space by having volume. Matter is made of atoms, and atoms are comprised of protons, neutrons, and electrons.
Explanation:
Atoms do not need food, water, and air; and they do not reproduce themselves. Cells are alive. Just as atoms have smaller parts called protons, neutrons, and electrons, cells have smaller parts, too. Each form of matter is made out of the same basic constituents: small particles called atoms.
