MCQ
A common character found in all plants with underground stem is:
- ✓Vegetative propagation.
- BFood stored in the stem.
- CA stem covered with scales.
- DA stem that grows horizontal to the earth.
These plants produce stems modified to store energy and preserve a location of potential growth to survive a cold or dry period which normally is a period of inactive growth, and when that period is over the plants resume new growth from the underground stems.
Being underground protects the stems from the elements during the dormancy period, such as freezing and thawing in winter or extreme heat and drought in summer or fire.
