Question

name the two kinds of cell in xylem tissue

Answer 1

1.Xylem parenchyma
2.xylem fibers
3.vessels
4.tracheids

Answer 2

Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. 

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.[1]

Xylem also contains two other cell types: parenchyma and fibers.[2]

Xylem can be found:

in vascular bundles, present in non-woody plants and non-woody parts of woody plantsin secondary xylem, laid down by a meristem called the vascular cambium in woody plantsas part of a stelar arrangement not divided into bundles, as in many ferns.

In transitional stages of plants with secondary growth, the first two categories are not mutually exclusive, although usually a vascular bundle will contain primary xylem only.

The branching pattern exhibited by xylem follows Murray's law.
they are living.
