                                Botanically speaking, a sweet potato is a storage root, not a true stem tuber like a regular potato. This often-misunderstood classification stems from the fact that while both are underground storage organs, their origins within the plant are entirely different. The sweet potato is a fleshy, adventitious root, modified specifically to store starch, not a thickened underground stem.
