3 CELL THEORY Cells are the basic units of & of all living things Cells are the basic units of structure & function of all living things All cells carry on life functionsprocesses All cells carry on life functions (processes) Cells arise only from cells Cells arise only from preexisting cells Organisms can be (Ex. ) OR (Ex., ) Organisms can be unicellular (Ex. bacteria) OR multicellular (Ex. plants, animals)
