The elongation zone of the root tip is where a majority of the growth in length occurs.
Explanation:
The zone of elongation is a region where newly formed cells increase in length, producing a great deal of the actual change in length, as new cells are quite small.
One could also argue that the apical meristem, as it is the source of all new cells in the root, is the primary driver of root growth. The meristematic region is the zone where the most active cell division occurs - all of the new cells are produced at the apical meristem, which defines the primary axis or direction of growth. Without new cells, the length of the root will be very limited.
