Potato tuber is an underground stem which is vegetatively propagated. Each tuber bears eyes or nodes from which the new growth begins. Each eye bears buds from which the new stem emerges as a sprout and the sprouts give rise to new plant. Number of eyes and distribution is characteristic of the variety. Sprouts appear from the eyes of the primary tuber. The sprouts emerge after their dormancy period is over. The cut potato with an eye is the seed. A corky layer develops around the seed that prevents decaying.

The potatoes bought from the market after a fortnight developed sprouts. I took a portion and cut thin slices to observe it under a foldscope. The suberized portions and the emerging young stems could be marked in T.S of sprout.
