en.wikipedia.org/wiki/Vascular_bundle

Bundle-sheath cells are photosynthetic cells arranged into tightly packed sheaths around the veins of a leaf. They form a protective covering on leaf veins, and consist of one or more cell layers, usually parenchyma. Loosely arranged mesophyll cells lie between the bundle sheath and the leaf surface. The Calvin cycle is ...

In monocots, xylem and phloem are organized in vascular bundles scattered throughout the stem. As the plant grows, monocot stems generate new vascular bundles for the new tissue. Monocot stems in general possess a simpler arrangement than that found in dicots; the main elements of the stem are merely the vascular ...

The space between the phloem and xylem is filled in with either parenchyma or fibres, or both. In some cases the vessels of the xylem meet in the centre of the root, while in other cases the centre of the stem is occupied by pith parenchyma. Each bundle is surrounded by parenchyma cells, and in iris, calamus, and veratrum, ...

They occur adjacent to Xylem in the bundle, partly or wholly surrounding the latter. Some workers are of opinion that transfusion tissue derives its origin from centripetal xylem, while others consider it to be transformed parenchyma cells outside the vascular tissues. Their function is uncertain. But as they connect the veins ...
