Do all cells of a plant contain chloroplasts?
Not all cells of the plant contain chloroplasts, but they all contain some form of plastid. When the plant is its development state, they contain proplastids which may turn into chloroplasts if the cells are exposed to light. Other forms of plastids may play a role in storing lipids, amylum or proteins and they form because there is a lack of light (these are present mostly in roots). Chloroplasts are not eliminated from the cell.

This is a very general explanation though and you should look more into hormones and specific triggers for the formation of chloroplasts.
