Biological Classification
  1. The cells of the quiescent centre are characterised by
    1. dividing regularly to add to tunica
    2. having dense cytoplasm and prominent nuclei
    3. having light cytoplasm and small nuclei
    4. dividing regularly to add to the corpus
Correct Option: C

The cells of queiscent centre have lower concentration of DNA, RNA and protein as compared to other cells in the root apex. These cells do not divide, hence cytoplasm is light and nuclei are small in them. This concept is based upon quiescent centre theory proposed by Clowes (1961).
