The cells of the quiescent centre are characterised by:
The cells of the quiescent centre are characterised by:
having dense cytoplasm and prominent nuclei
having light cytoplasm and small nuclei
dividing regularly to add to the corpus
dividing regularly to add to tunica
Solution
According to Quiescent Centre Theory, root apical meristem is present as the tip of main root and has a biconvex quiescent centre in its centre which is characterized by presence of inactive cells with less number of cell organelles, light cytoplasm, small nuclei and low synthesis of DNA, RNA and protein caused by low frequency of cell division, mitosis.

Behind the root cap is the quiescent centre. a region of inactive cells. They function to replace the meristematic cells of the root cap meristem. The quiescent centre is also important in organizing the patterns of primary growth in the root.
