Vocabulary:
Atom~A unit of matter; the smallest unit of a chemical element.
Nucleus~the central part of most cells that contains genetic material and is enclosed in a membrane (found in most living eukaryotic cells)
Molecule~a group of atoms bonded together
Element~any material (such as carbon, hydrogen, iron, or oxygen) that cannot be broken down into more fundamental substances
Compound~a thing that is composed of two or more separate elements; a mixture.

Cell Division~the division of a cell into two daughter cells with the same genetic material.
Cell Cycle~a series of events that takes place in a cell as it grows and divides
Mitosis~a type of cell division that results in two daughter cells each having the same DNA
