Final answer:
Tubers, like potatoes, can produce new plants through vegetative propagation, while seeds cannot.
Step-by-step explanation:
Tubers, such as potatoes, have a unique ability that seeds do not possess: they can produce new plants by vegetative propagation. This means that a single tuber can give rise to multiple new plants that are genetically identical to the parent plant. In contrast, seeds are the result of sexual reproduction and can produce new plants that show genetic variability.
