A tuber is a specialized underground storage structure found in certain plants, serving as a reservoir for storing energy and nutrients. It typically develops from swollen, underground stems or roots and contains buds or "eyes" from which new shoots can grow. Potatoes are a well-known example of tubers, forming from the thickened, underground stems of the potato plant. Tubers provide a source of food and energy for the plant during periods of dormancy or adverse conditions. They are also a valuable food source for humans and animals and are cultivated as a staple crop in many regions of the world.
