Final answer:
Specialization is another way to say that all cells perform various jobs. In biology, cell differentiation refers to the process by which cells become specialized to perform distinct functions.
Step-by-step explanation:
Another way to say 'all cells perform various jobs' is specialization. In biology, cell differentiation refers to the process by which cells become specialized to perform distinct functions. All cells in the body contain the same DNA, but each type of cell reads only the portions of DNA that are relevant to its own function. This unique genetic expression of each cell allows for the specialization of different cell types to perform specific jobs.
