Answer:
A negative control would show you what negative results should look like. The positive control ensures that the experiment worked correctly and gives you something to compare your results to. You could use selective growth to select for cells that were transformed (maybe they picked up resistance to a certain antibiotic and you grow your samples on media with that antibiotic).

The difference is that one gives you a positive result while the other gives a negative result. The positive control shows you that your assay worked correctly. The negative control shows your background results. It is the experiment run without the experimental variable.
