Rhizome of ginger is like the roots of other plants that grows underground. Despite this ginger is a stem not a root. Justify.

Solution:

Ginger rhizome is classified as a stem based on the following anatomical and morphological features:

1. Nodes and internodes are present
2. Scale leaves arise at nodes
3. Axillary and terminal buds present (roots lack buds)
4. Grows horizontally underground
5. Adventitious roots arise from the lower surface

These characteristics confirm it is a modified stem, not a root.
