Answer:
Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
Explanation:
The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels.[6]
Xylem also contains two other cell types: parenchyma and fibers.[7]
Xylem can be found:
in vascular bundles, present in non-woody plants and non-woody parts of woody plants
in secondary xylem, laid down by a meristem called the vascular cambium in woody plants
as part of a stelar arrangement not divided into bundles, as in many ferns.
