Growing Potatoes

Growing Potatoes

I found some potatoes that were under my cabinet and they were already growing, so I thought that I would plant them. The problem is that I'm not sure how to plant them. I feel foolish asking this but are these the tops or the roots? Can anyone please help? I've enclosed a pic so you all can see what I'm talking about. Thanks Photobucket
