Distinguish between the following: Stele and vascular bundle.
(N/A) The differences between Stele and Vascular bundle are as follows:
| Feature | Stele | Vascular bundle |
| :--- | :--- | :--- |
| Definition | It is the central part of the root or stem,internal to the endodermis. | It is a strand of conducting tissue consisting of xylem and phloem. |
| Components | It includes the pericycle,vascular bundles,and pith. | It consists of xylem and phloem,and sometimes cambium in dicots. |
| Scope | It represents the entire central core of the plant axis. | It is a specific unit of the conducting system found within the stele. |
