Question

Other than the main functions that almost all stems perform, there are other specialised functions performed by stems of some plants. Name two such plants and the specialised function performed by their stems.

Answer 1

In addition to the main functions such as conduction of water, food and minerals, stems can perform following specialised functions:

1. Provide support: In case of grapewine, the stem is modified into minute thread-like structures called stem tendrils. These stem tendrils have the ability to coil around any rough surface and provide support to the plant.

2. Store food: In case of ginger, the stem is modified to store food. The stem in this case lies underground and functions to store additional food material.
