Options
- Atissue located below the phloem bundles and a portion of pericycle tissue above protoxylem
- Bcortical region
- Cparenchyma between endodermis and pericycle
- Dintrafascicular and interfascicular tissue in a ring
Correct answer
A. tissue located below the phloem bundles and a portion of pericycle tissue above protoxylem
Step-by-step solution
In dicot root, the vascular cambium originates from tissues located below the phloem bundles and a portion of pericycle tissue above protoxylem. Vascular cambium is the meristematic layer that is responsible for cutting off vascular tissues (xylem and phloem). In young stem, it is present in patches as a single layer between the xylem and phloem.
