Roots grow longer because of cell division in the:
AApical meristem (at the root tip)
BLateral meristem
CIntercalary meristem
DPhloem
Answer & Solution
Correct answer: A. Apical meristem (at the root tip)
Apical meristems sit at the tips of roots and shoots. Their division pushes the tip forward (in roots: downward into the soil), increasing length. If you cut off the root tip, longitudinal growth stops — which is why pruning a plant tip stunts vertical growth.
