Atom - An atom is the smallest unit of an element that has chemical properties of the element. All matter is composed of atoms Molecules and Macromolecules - Atoms bond with each other to form molecules. A polymer such as a polypeptide is formed of many molecules bonded together and is called a macromolecule. Carbohydrates, proteins, and nucleic acids (DNA and RNA) are important macromolecules found in living organisms. Cells - The simplest unit of life is the cell. A cell is surrounded by...
