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 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 inner core of the root, known as the stele, is primarily composed of vascular tissue, including xylem and phloem. The xylem is responsible for transporting water and minerals from the soil to the rest of the plant, while the phloem distributes the products of photosynthesis, such as sugars, throughout the plant. Additionally, the pericycle, a layer of tissue surrounding the vascular tissue, plays a role in root growth and the formation of lateral roots. Together, these tissues facilitate essential functions for the plant's nutrient and water uptake.
Tissues in a plant root are distributed in layers: the outermost layer is the epidermis, followed by the cortex, endodermis, and pericycle. In the center of the root is the vascular tissue called the stele, which includes the xylem and phloem. Each of these tissues plays a unique role in the absorption, transport, and storage of water, nutrients, and sugars in the plant.
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.

Plants such as carrots or celery stalks are composed of vascular tissue.
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.
