Is done within the fields of taxonomy and systematics. All organisms are related to each other and descend from a common ancestor. The three domains of life: bacteria prokaryotes, unicellular, minimal internal structure, lack membrane-bound internal compartments, archaea (cid:862, eukaryotes unicellular or multicellular, highly structured interior, many membrane-bound structures (organelles) The cell theory: all organisms are composed of cells, cells are the smallest living things, cells arise only from pre-existing cells. All cells today represent a continuous line of descent from the first living cell. Atom molecule macromolecule organelle cell. Cell tissue organ organ system organism.
