Q. For a critical study of secondary growth in plants, which one of the following pairs is suitable?
A) teak and pine
B) deodar and fern
C) wheat and maiden hair fern
D) sugarcane and sunflower
Explanation
[Solution from source] Teak (a dicot tree) and pine (a gymnosperm) both have an active vascular cambium and cork cambium, so they show clear secondary growth. Ferns, wheat and sugarcane lack cambial activity, so every other pair contains a plant without secondary growth. Answer (1).
