Solution
The concept of quiescent centre was proposed by Clowes in $1961.$ On the basis of autoradiographic studies of DNA synthesis in the root tip of Zea, he found a reservoir of cells having low DNA, RNA and protein concentration. He called it quiescent center. They may or may not divide. It is resistant to damage.
