Question

Quiescent centre is found in root apex and acts as

• A. permanent source of active initiates
• B. reservoir of resistant cells
• C. reservoir of passive cells to form new root apex if root apex is damaged/killed
• D. All of the above

Answer 1

Answer: (A)

Quiescent centre is a cup-shaped zone of inactive cells in the root apex of angiosperm. Normally, the cells of the quiescent centre do not divide. The cells of the quiescent centre become active, whenever the active initials are damaged. It also acts as reservoir of cells relatively resistant to damage.
