Unlike phloem, which does not accumulate but instead is shed with the dead bark, the old xylem is retained, may be used to conduct water for a few years, and eventually just provides structural support as the tree grows larger. At least 90% or more of the trunk of a tree is xylem or wood.
Gk. xylon, wood] The tube-shaped, nonliving portion of the vascular system in plants that carries water and minerals from the roots to the rest of the plant.
Woody tissue of a plant. Xylem transports water and nutrients from the roots to the leaves. It is a complex vascular tissue in plants; comprises vessels (hollow receptacles) and/or tracheids usually together with wood fibers and parenchyma cells, functioning in conduction (and also in support and storage). Xylem cells account for most of the diameter growth in a tree each year.
the structure of vascular plants that conducts water and minerals upward from the roots.
water conducting tissue in woody plants
cells in a tree that carry water and minerals from the roots to the trunk, branches and leaves A tree's water and minerals are moved around the tree in the xylem.
The supporting and water-conducting tissue of vascular plants; plant tissue consisting primarily of tracheids and vessels; woody tissue.
water-conducting, food-storing, and supporting tissue of roots, stems, etc.
The tissues of the stem and root lying between the pith and Cambium of a woody plant serving for water conduction, mechanical strength and food storage; characterized by the presence of tracheids or vessels. Syn. Wood. ( BCFT modif.).
Tissue used in plants to transport water and minerals.
the woody part of plants: the supporting and water-conducting tissue, consisting primarily of tracheids and vessels
Plant vascular organ composed of tissues that conduct water and dissolved nutrients from the roots upward throughout the plant body.
The supporting layer of tissue in vascular plants that conducts water and nutrients from the roots to other parts of the plant.
The tubes which carry water in a plant's stem.
The tissue responsible for the upward movement of water and nutrients from the roots of a plant to its leaves.
Vascular tissue composed of cells that are dead at maturity; transports water and dissolved minerals upward from the roots to the shoot.
Plant tissue through which all water and dissolved nutrients are conducted (see also tracheid and hydroid).
Vascular tissue specialized for the conduction of water. Cells of the xylem are dead at functional maturity, consisting only of primary and secondary cell walls.
Tissue in the vascular system of plants that moves water and dissolved nutrients from the roots to the leaves; composed of various cell types including tracheids and vessel elements. Plant tissue type that conducts water and nutrients from the roots to the leaves.
the tissue, in a vascular plant, that conducts water and mineral salts from the roots to the leaves.
a complex tissue in the vascular system of plants that consists of vessels and wood fibers, conducting water and dissolved minerals, and aiding in support and food storage. See also phloem
Area below cambium in the trunk.
This is a plant transport tissue. It transports water and minerals from the roots to other parts of the plant. Back to top of the page
"The botanical name for wood, which supports a tree and bungs the nutrients for growth. "
Water conducting tissue in plants (2) A plant tissue consisting of tracheids, vessels, parenchyma cells, and fibers; wood. (1)
A plant's water conducting vessel
The portion of the tree trunk, branches, and roots that lies between the pith and the cambium.
The woody tissue of the stem, branches, and roots that transports water and nutrients.
Plant vascular tissue (i.e. an internal network of vessels) that carries water and dissolved nutrients from the roots up to the other parts of the plant.
In vascular plants, xylem is one of the two types of transport tissue in plants, phloem being the other one. The word "xylem" is derived from classical Greek ξυλον (xylon), "wood", and indeed the best known xylem tissue is wood, though it is found throughout the plant.
