- BIt has nodes and internodes
- CIt lacks chlorophyll
- DMore than one of the above
- ENone of the above
Show answer and explanation
Correct answer: (b) It has nodes and internodes
Explanation
Ginger is an underground stem, a rhizome, because it has nodes and internodes, scale leaves and buds, which roots never have.
Storing food and lacking chlorophyll are also true of many roots (carrot, radish), so they do not prove it is a stem.
