- 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.
