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