Plant cells are eukaryotic cells that differ in several key respects from the cells of other eukaryotic organisms. Their distinctive features include: • A large central vacuole, a water-filled volume...

While parenchyma cells do occur within what is commonly termed the "xylem" the more identifiable cells, tracheids and vessel elements, tend to stain red with Safranin-O. Tracheids are the more primitive of the two cell types, occurring in the earliest vascular plants.

; The xylem is a complex tissue. There are two types of sclerenhyma conducting cells in the xylem, the tracheids and vessel elements. The term tracheary element is sometimes used to refer to these cell types. ;

Brief and Straightforward Guide: What Is a Xylem Cell? ... A xylem cell is a cell which is responsible for providing support to a plant. Xylem cells also make up the vascular system of plants, conducting water throughout the plant and providing circulation.

The xylem is the principal water-conducting tissue of vascular plants. It consists of tracheary elements, tracheids and wood vessels and of additional xylem fibres. All of them are elongated cells with secondary cell walls that lack protoplasts at maturity.

Furthermore, mtZeHB-12 overexpression did not induce TE-specific genes, including genes related to programmed cell death and lignin polymerization, but did induce lignin monomer synthesis-related genes, which are expressed in xylem parenchyma cells.

Ha et al., 1998 ). At least three CesA genes are required for cellulose synthesis in the secondary cell walls of developing xylem vessels: IRX3 (AtCesA7) (Taylor et al., 1999 ), IRX1 (AtCesA8) (Taylor et al., 2000 ), and IRX5 (AtCesA4) (Taylor et al., 2003 ). These three proteins interact with each other,
