Question

A common character which not found in plants with under- ground stems is - (1) Stem covered with scale leaves (2) Food stored inside the stem (3) Vegetative reproduction (4) A stem that grows horizontal to earth​

Answer 1

Answer:

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.[4] 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. So, the correct option is A..(Vegetative propagation)
