The driving force that pushes the root tip through the soil is primarily
A) continuous cell division in the root cap at the tip of the root.
B) continuous cell division just behind the root cap in the center of the apical meristem.
C) elongation of cells behind the root apical meristem.
D) the elongation of root hairs.
E) continuous cell division of root cap cells.

Question

Quizplus · Accepted Answer

The elongation of cells behind the root apical meristem is the primary driving force that pushes the root tip through the soil. While continuous cell division is important for root growth, it alone does not explain the physical movement of the root tip through the soil. Elongation of root hairs also plays a role in nutrient absorption, but is not the primary driving force for root growth.
