Tubers are a class of plant which have large, fleshy, bodies as part of their structure. Tubers may be 'stem' tubers or rhizomes. The tubers are used to store nutrients for survival during winter and dry periods, during which the plant goes dormant to save energy, and as a means of asexual reproduction, being used as a base for generation of new plants which form mini-tubers around the main tuber. Tubers are a highly successful plant structure, and include some very well known types of plant. Some plants, like Mignonette vines, have aerial tubers, which fall from vines and grow new plants.
Examples of Tubers:
Freshly dug sweet potato plants with tubers.
