Answer 1

They store energy in their roots, similar to how seeds store energy. This is why they make for such a good food source. In the right conditions the vegetables will start metabolizing the stored energy in order to sprout a new plant. Once the first leaves are in place and the roots starts forming the plant have likely run out of energy but by then it collect its own energy.
