Stems can be modified to perform a variety of functions. Stems that are underground like Potato, ginger, turmeric, zaminkand, and Colocasia have been modified to store food.
They also serve as organs of perennation, allowing them to survive in unfavourable growth conditions.
Stem tendrils, which emerge from axillary buds and are slender and spirally coiled, aid in the climbing of plants such as gourds (cucumber, pumpkins, and watermelon) and grapevines.
Stem’s axillary buds can also be transformed into woody, straight, and pointed thorns.
Grass and strawberries, for example, spread their underground stems to new niches and when older parts die, new plants emerge. A slender lateral branch emerges from the base of the main axis in plants such as mint and jasmine and after growing aerially for a time arch downwards to touch the ground.
