Question

The apical meristem of the root is present

• A. Only in radicals
• B. Only in tap roots
• C. Only in adventitious roots
• D. In all the roots

Answer 1

The correct option is D In all the roots

A meristem is the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place. Meristematic cells give rise to various organs of the plant and keep the plant growing. The shoot apical meristem (SAM) gives rise to organs like the leaves and flowers, while the root apical meristem (RAM) provides the meristematic cells for the future root growth. Unlike the shoot apical meristem, the root apical meristem produces cells in two dimensions. It harbors two pools of stem cells around an organizing centre called as the quiescent center (QC) cells and together produce most of the cells in an adult root. The apical meristem of the root is present in all roots.
Thus, the correct answer is option D.
