Ok, for the mitochondrion you might want to wait for me to rework it like the chloroplast one as the article version is a bit messy right now. And why are you using image map—the whole point of the text labels is the underlines and people being able to highlight the diagram and see the text (useful for accessibility reasons). & as it seems youre using File:Mitochondrion mini.svg instead of the article version, I would uggest you design at 300px because this solution isnt scalable.—Love, '''''' talk
