Conjoint, open and endarch vascular bundles arranged in a ring are diagnostic of
AA typical isobilateral leaf vein section
BA typical dicotyledonous stem cross section
CA typical monocotyledonous stem cross section
DA typical dicotyledonous root cross section
Answer & Solution
Correct answer: B. A typical dicotyledonous stem cross section
Dicot stem: conjoint (X and P same radius) + open (cambium present) + endarch (protoxylem internal) + ring of bundles. This combination is unique to the dicot stem and is the textbook diagnostic image.
