allerySecondary growth in plants is brought about primarily by:
AApical meristems at root and shoot tips
BIntercalary meristems between mature tissues
CLateral meristems (vascular cambium + cork cambium)
DSclerenchyma tissues in vascular bundles
Answer & Solution
Correct answer: C. Lateral meristems (vascular cambium + cork cambium)
Secondary growth (increase in GIRTH) is driven by lateral meristems: VASCULAR CAMBIUM (produces secondary xylem + phloem) and CORK CAMBIUM (produces cork).
Apical = primary (length); intercalary = regrowth.
