Question
Quiescent centre is the zone of
least mitotic activity in the root apex
least mitotic activity in the shoot apex
maximum mitotic activity in the root apex
maximum mitotic activity in the shoot apex
Solution
A.
least mitotic activity in the root apex
Quiescent centre is an area at the top of the root apical meristem where the cells have least mitotic activity i.e., the rate of cell division is lower than in surrounding tissue. But the cell retains the meristematic property ones the meristamatic cells sourrounding them are damaged.
