A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in vascular tissue, which exists in two forms: xylem andphloem. Both these tissues are present in a vascular bundle, which in addition will include supporting and protective tissues. Also, it is a vein in the leaf that contains conducting tissues.The xylem typically lies adaxial with phloem positioned abaxial. In a stem or root this means that the xylem is closer to the centre of the stem or root while the phloem is closer to the exterior. In a leaf, the adaxial surface of the leaf will usually be the upper side, with the abaxial surface the lower side. This is whyaphids are typically found on the underside of a leaf rather than on the top, since the sugars manufactured by the plant are transported by the phloem, which is closer to the lower surface.
The position of vascular bundles relative to each other may vary considerably: see stele.

Vascular bundle arrangement
The vascular tissue in the stem is found in the steler region. It extends from the conducting cells of the seedling.
The vascular tissue of a plant stem is surrounded by a layer of cells known as the endodermis. The endodermis is responsible for regulating the movement of water and nutrients into and out of the vascular tissue.
Xylem and phloem are typically found in the vascular tissue of plants. In stems, xylem is located towards the center while phloem is closer to the outer edge. In roots, xylem is towards the center and phloem surrounds it.

This structure is called a vascular bundle or a stele. It is found in the center of plant stems and roots, surrounded by parenchyma cells that provide support and store nutrients. Vascular bundles contain xylem for water transport and phloem for nutrient transport in plants.

Stomata
The primary source of stem thickening in plants is the vascular cambium, a layer of cells between the xylem and phloem tissues. The vascular cambium is responsible for producing new xylem and phloem cells, which leads to an increase in stem girth over time.
In monocot stems, vascular bundles are scattered throughout the ground tissue. They are not arranged in a distinct pattern like in dicot stems where they form a ring. The scattered distribution of vascular bundles provides support and strength to the stem.
Xylem and phloem are typically found in the vascular tissue of plants. In stems, xylem is located towards the center while phloem is closer to the outer edge. In roots, xylem is towards the center and phloem surrounds it.
There are three types of stem cells commonly found in the body: embryonic stem cells, induced pluripotent stem cells, and adult stem cells. Each of these stem cell types has different properties and capabilities for differentiation and regeneration.
