Definition Of Xylem And Phloem

Phloem is the other type of transport tissue.

Definition of xylem and phloem. Phloem is the complex tissue which acts as a transport system for soluble organic compounds within vascular plants. Xylem definition a compound tissue in vascular plants that helps provide support and that conducts water and nutrients upward from the roots consisting of tracheids vessels parenchyma cells and woody fibers. Phloem definition the part of a vascular bundle consisting of sieve tubes companion cells parenchyma and fibers and forming the food conducting tissue of a plant. The other material that makes up the vascular plant transport system.

Xylem tissues are the tubular shaped structure with the absence of cross walls. During transpiration water evaporates from the leaves and draws water from the roots. Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves. Phloem tissues are tubular shaped elongated structures with the presence of walls with thin sieve tubes.

It usually contains a large proportion of woody fibrous cells and is therefore the part from which the fibre of the plant is obtained as that of hemp etc. Xylem moves water from roots to the leaves and phloem moves food from the leaves to the rest of the plant. This tissue resembles the shape of a star.

In woody plants particularly trees the phloem is the innermost layer of the bark next to the wood. They are the vascular tissues that transport substances throughout the plant. In a tree trunk the innermost part of the wood is dead but structurally strong xylem while the outer part consists of living xylem and beyond it layers of cambium and phloem. Phloem definition is a complex tissue in the vascular system of higher plants that consists mainly of sieve tubes and elongated parenchyma cells usually with fibers and that functions in translocation and in support and storage.

The phloem is made up of living tissue which uses turgor pressure and energy in the form of atp to actively transport sugars to the plant organs such as the fruits flowers buds and roots.
