Answers (1)
According to the Quiescent Centre Theory, the quiescent centre refers to a specific region within the root apical meristem of a plant. It is located between the root cap and the actively dividing cells of the apical meristem. The quiescent centre is characterized by several features:
- It contains inconspicuous nuclei, which are not actively dividing.
- It has limited cytoplasmic content, including the presence of endoplasmic reticulum and some mitochondria.
- It acts as a reservoir of meristem cells that can become activated and divide when needed for growth or repair.
Therefore, all of the statements mentioned in Option 4 are correct. The quiescent centre is a specialized region that functions as a reservoir of meristem cells, characterized by specific cellular features and its position within the root apical meristem.
