(C) The concept of the quiescent centre was proposed by $Clowes$ in $1961$.Based on autoradiographic studies of $DNA$ synthesis in the root tip of $Zea$ $mays$,he identified a region of cells with low $DNA$,$RNA$,and protein concentrations.He termed this region the quiescent centre.These cells are characterized by a low rate of division but can become active to replenish damaged cells of the meristem,acting as a reserve pool.
