Apples: Organic vs. Non-Organic

I was working the other morning in the produce section putting away some apples, when I noticed the major difference between some of the apples that are organic and others that are non-organic. Both of the apples are Gala apples but they look nothing alike. The apple sitting on the left is organic,while the right one is non-organic. I'd be inclined to say that the non-organic apple looks more like a Red Delicious than a Gala. Anyway, I thought they both looked nice and I'd like to practice food photography a little more-- this seemed like a good starting point.
