In the dicot root the vascular cambium originates from:

1. Intrafascicular and interfascicular tissue in a ring.
2. Tissue located below the phloem bundles and a portion of pericycle tissue above protoxylem.
3. Cortical region
4. Parenchyma between endodermis and pericycle.

Correct answer: Tissue located below the phloem bundles and a portion of pericycle tissue above protoxylem.

Solution

In dicot roots, the vascular cambium is not formed from fascicular and interfascicular regions as in stems. It develops from the tissue below the phloem bundles along with a part of the pericycle above the protoxylem, which later joins to form the cambial ring.
