In which part of a plant would you not expect to find cells with chloroplasts?

The part of the plant where there would be no chloroplast would be the ROOT.
This is be because the root is mostly underground and as such there would be no sunlight for the light stage of photosynthesis and ultimately would not be conducive to the process occurring.  Thus by adaptation, the root cells lack chloroplasts. 

Distillation.  distillation is the correct answer.
