What is a tuber?

A tuber is defined as a fleshy, oblong or rounded thickening of a subterranean stem or shoot. This specialized structure functions primarily as a storage organ, allowing plants to store nutrients and energy, which is essential for growth and reproduction. Tubers are typically made up of plant tissues that are rich in starch, and they play a critical role in the plant's lifecycle, providing a means for vegetative reproduction and survival during unfavorable conditions.

This understanding is crucial not just for plant biology but also for working with plants in a landscape management context, including pest control and horticulture. Recognizing plant structures like tubers enables better decision-making about plant care and pest management strategies.
