I'm having bit of a trouble on my lab with that and this question "What structures were visible after staining that were not visible before the staining of the onion cell with iodine?" "How are mitochondria and chloroplasts similar and different (strcture and function)?" If your lazy and know that a site that has one or all of these answers please link it thanks.

Elodea cell have chloroplasts, onions don't.
When you stain the onion cell with iodine you are staining the starch, the vacuole should become visible.
Mitochondria and chloroplasts are both organelles in the cell, chloroplasts are responsible for photosynthesis, mitochondria are responsible for respiration.

Because they grow underground and have no use for them in total darkness.
