Root Hairs on a Root Develop

Question

Root hairs on a root develop
A) on the entire root surface.
B) on the root cap.
C) after the cells elongate.
D) before the cells elongate.

Accepted Answer

Root hairs develop after the cells elongate, as they arise from the elongated epidermal cells of the root. They do not develop on the entire root surface or on the root cap, and they form after elongation, not before.
