Stems of various plants have undergone modifications to perform different functions.1. Underground stems or storage stems:Examples: Rhizomes, Corms, tubersIn ginger and banana, the underground stem is called as a rhizome. The underground stem in Colocasia (arvi) is known as corm. Rhizomes and corms are underground stems, modified for the storage of food. Also, these stems help in vegetative reproduction of these plants. The tips of the underground stem in potato plants become swollen due to the accumulation of food. The potato is a tuber that helps in the storage of food and bears eyes on it. Subtended by a leaf scar, these eyes bear buds that give rise to new plants.
