You can't "kill" a plant in the same way you can kill an animal. Chunks of plant matter are generally alive until they've been without water long enough for the cells to start popping. A potato has a lot of water in it. There's no way to "kill" a potato.
The stuff-that-grows in the potato is the eyes. You'd have to kill each of them.
As others say, breaching the skin (which is basically a protective wax coat) is what would let it start to dry out, get infected, and decay. The part of the potato you eat is a bunch of starch-storage cells; I'm not sure if they even metabolize anything.

Plants have much less of a distinct identity than people do. You can cut them into pieces and get multiple individuals.
