Document Summary

Atom: smallest particle of an element with all the properties of that element. Molecule: smallest amount of a substance that can exist alone = a combo. of atoms. Organelle: molecules associate in specific ways to form organelles = basic component of living cells. Cell: fundamental, structural and functional unit of a living thing. Tissue: groups of similar cells that have a common function. Organ: structure composed of at least 2 (but usually 4) tissue types that performs a specific function for the body. Organ system: organs that work closely with one another to accomplish a common purpose. They come in many different shapes and sizes; reflecting unique functions in the body. Membrane made of double layer of lipids (phospholipids, cholesterol, and so on) within which proteins are embedded. Serves as an external cell barrier, and acts in transport of substances into or out of cell.
