[Short Answer Section]
The three parts of the cell theory are: the cell is the unit of function of living things, the cell is the unit of structure of living things, and all cells come from preexisting cells.
Three possible exceptions to the cell theory could be: 1.) where did the 1st cell come from? 2.) viruses are usually incapable of independent replication and lack certain cell structures 3.) some organisms lack typical cellular organization (slime molds and some muscle cells).
