What is the difference between atoms molecules organelles and cells?

Atoms are the basic building blocks of matter, consisting of protons, neutrons, and electrons. Molecules are formed when two or more atoms bond together, creating substances with specific chemical properties. Organelles are specialized structures within cells that perform distinct functions, such as energy production or protein synthesis. Cells are the fundamental units of life, made up of organelles and surrounded by a membrane, capable of carrying out all necessary life processes.
