Origin of xylemGerman from Classical Greek xylon, wood
Xylem vessels in a leaf skeleton.
Xylem is a type of tissue in plants that carries water.
An example of xylem is what moves water and some nutrients through a plant.
the woody vascular tissue of a plant, characterized by the presence of vessels or tracheids or both, fibers, and parenchyma, that conducts water and mineral salts in the stems, roots, and leaves and gives support to the softer tissues
The tissue of vascular plants that conducts water and minerals, provides support, and consists of tracheary elements and parenchyma cells. Woody tissue is made of secondary xylem produced by the vascular cambium.
Origin of xylemGerman from Greek xulon wood
From German Xylem, from Ancient Greek Î¾ÏÎ»Î¿Î½ (ksulon, “wood").
- Xylem and protophloem alone are differentiated) being very much shorter than in the stem.
- Differentiation of the xylem progresses outwards, of the phloem inwards, but the two tissues never meet in the centre.
- The xylem being centrifugal and the m, Medullary bundles.
- After the cambium has been active for some time producing secondary xylem and phloem, the latter consisting of sievetubes, phloem-parenchyma and frequently thick-walled fibres, a second cambium is developed in the pericycle; this produces a second vascular zone, which is in turn followed by a third cambium, and so on, until several hollow cylinders are developed.
- Occasionally happens that groups of (After Worsdell.) xylem and phloem are developed pd, Periderm in leaf-bases.
