NEETBotanyAnatomy of Flowering Plants
In a dicotyledonous root, the cells of the pericycle are responsible for the initiation of:
Options
- Alateral roots and vascular cambium
- Broot hairs and primary xylem
- CCasparian strips and conjunctive tissue
- Dlateral branches of stem and cork cambium
Correct answer
A. lateral roots and vascular cambium
Step-by-step solution
In a dicotyledonous root, the pericycle is the layer of cells located just inside the endodermis. According to NCERT, the initiation of lateral roots and the vascular cambium during secondary growth takes place in these pericycle cells. Root hairs arise exogenously from the outermost layer (epiblema). Casparian strips are a characteristic feature of the endodermis, not the pericycle. Lateral branches of stems have an exogenous origin, unlike the endogenous origin of lateral roots from the pericycle. Answer: lateral
