3rd Mar, 2022
Modifications of stems occur to perform specialized functions apart from their usual role of support and conduction. These modifications include:
1. Underground stems – Tubers (potato) store food, Rhizomes (ginger) help in vegetative propagation, and Bulbs (onion) store nutrients.
2. Subaerial stems – Runners (grass) and Stolons (strawberry) help in vegetative propagation by spreading on the ground.
3. Aerial stems – Tendrils (cucumber) provide support by climbing, Thorns (citrus) protect the plant, and Phylloclades (cactus) store water in arid conditions.
