alleryVascular bundles in roots have xylem and phloem arranged
AIn scattered bundles across cortex
BRadially on different radii
CConjointly along same radius
DBicollaterally around a central pith
Answer & Solution
Correct answer: B. Radially on different radii
Radial arrangement = xylem and phloem on different radii (typical of roots).
Conjoint = same radius (typical of stems and leaves).
Bicollateral = phloem on both sides of xylem (some Cucurbitaceae).
