Chapter 33, Problem 4Q

Summary Introduction

To review:

Quiescent center (QC) serves as the reservoir of stem cells that ensures the continued growth of the root apical meristem and the pattern of labeling in QC supporting this thesis.

Introduction:

The root apical meristem (RAM) consists of a central region in which the cells either do not divide or divide very slowly but can resume their dividing ability when needed. The cells of QC undergo division to form initial cells that later gives rise to primary root tissues.
