Do onion cells still have chloroplasts when they have iodine on them?

The iodine has no connection as to whether the cells have chloroplasts or not. If the cells are green, then they do have them. Adding iodine doesn't change that fact. Not all cells of the plant have chloroplasts. The ones in the soil don't so if you are working with the bulb, it doesn't have chloroplasts in the first place.
