Xylem consists of three different types of cells: Xylem parenchyma cells and xylem fiber cells, which simply provide structural support for the most important xylem cells, the tracheary elements (TE). The TE are completely dead at maturity, and act like pipes to allow water and dissolved minterals to flow through them. There are two types of tracheary elements: vessel elements and tracheids. Though they have some structural differences, these two types function in the same manner.
Adaption of Xylem vessel are: 1. thick wall made of lignin which supports the plant. 2. xylem vessel are hollow from inside.3. does not have cross walls, are hollow from ins â¦ ide which increase the surface area to volume ratio and can take in more water.he most distinctive cells found in xylem are the tracheary elements, that is tracheids and vessel elements. However, the xylem is a complex tissue of plants, which means that â¦ it includes more than one type of cell. This is why it is a tissue not a cell. 2 people found this useful.
