- A The typical, predictable secondary growth pattern that most dicot stems generally follow
- B Secondary growth that does not follow the typical pattern, found in some climbers and monocots
- C Secondary growth that occurs mainly within the root system rather than the stem
- D Vegetative growth occurring within non-vascular mosses and liverworts over time
Correct answer: B. Secondary growth that does not follow the typical pattern, found in some climbers and monocots
Explanation: Anomalous (atypical) secondary growth deviates from the normal pattern. It occurs in some dicot climbers (Bignonia, Dracaena) and some monocots (Agave, Yucca). It involves additional cambium rings or development outside typical positions.
Concept context
Internal tissue organisation: meristems, permanent tissues (xylem, phloem, parenchyma), and secondary growth. Frequently tested in NEET.
