- Support
Stems provide complete support to the plant.
- Conduction of substances
Stems transport the water from roots up to the leaves and the food prepared by leaves to all the other parts.
● Photosynthesis
In some plants, stems are green coloured and thus, perform photosynthesis.
● Storage of food
In some plants, stems function as a food storage bag. For example, potato, onion, and garlic.
