The zone of elongation is responsible for pushing the root deeper into the soil. This is where cells are actively elongating and pushing the root tip downwards. The other regions (root cap, root apical meristem, zone of cell division, and zone of maturation) all play important roles in root growth and function, but they are not directly responsible for pushing the root deeper into the soil.
