The endodermis, a specialized layer of cells, surrounds and borders the stele of a dicot root. It is responsible for regulating the passage of water and nutrients into the vascular tissues of the root.
Plants such as carrots or celery stalks are composed of vascular tissue.
The stele is the central part of a plant's root or stem that contains the vascular tissue, primarily xylem and phloem, responsible for the transport of water, nutrients, and sugars throughout the plant. It plays a crucial role in supporting the plant's overall structure and facilitating communication between different plant parts. Additionally, the stele can help in the storage of nutrients and contribute to the plant's growth and development.
The inside of roots contains a central vascular tissue called the stele, surrounded by layers of cells including the endodermis, cortex, and epidermis. The stele is responsible for transporting water and nutrients throughout the root system, while the other layers provide protection and support.
The size of the stele in monocots is typically smaller compared to dicots. Monocots have scattered vascular bundles in their stele, whereas dicots have a more organized arrangement. This difference reflects the distinct vascular organization patterns between the two groups.
The vascular tissue of primary roots is aggregated into a structure known as the vascular cylinder or stele. This central region typically contains xylem and phloem arranged in a specific pattern, often with xylem located toward the center and phloem located outside. In some plants, the vascular tissue may also be surrounded by a pericycle, which plays a role in root growth and branching.
Monocots do not have pith inside of them. They do have vascular bundles however, which are in a scattered order.
The innermost cylinder of a root is composed of vascular tissue called the stele. The stele consists of the vascular tissues xylem and phloem, which are responsible for transporting water, nutrients, and sugars throughout the plant.
In the stele, which is the central cylinder of vascular tissue within the root.

Stele
Xylem is part of the vascular tissue of plants, and the xylem and phloem together are grouped together as the stele (latin for 'pillar'). Xylem tissue is encased in lignin, the substance that creates the strength of wood, causing the protoplasm (living part of the cell) to die, and therefore be dead tissue; phloem is living tissue.

A stele is a monument marker, usually taller than it is wide.Her grave is marked by a stone stele.The stele marked where the famous battle was fought.
