Consider the given statements:
| I. | In dicot roots, the pericycle strengthens the roots and provides protection for the vascular bundles. | 
| II. | In dicot root, the vascular cambium is completely secondary in origin, and it originates from a portion of pericycle tissue. | 
| III. | The pericycle regulates the formation of lateral roots by rapidly dividing near the xylem elements of the root. | 
The correct statements are:
| 1. | Only I and II | 2. | Only I and III | 
| 3. | Only II and III | 4. | I, II and III | 
A major characteristic of the monocot root is the presence of:
| 1. | Scattered vascular bundles | 
| 2. | Vasculature without cambium | 
| 3. | Cambium sandwiched between phloem and xylem along the radius | 
| 4. | Open vascular bundles |
