Xylem Definition Biology Igcse
The xylem and phloem are grown within the central section of a root called a stele.
Xylem definition biology igcse. Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves. Xylem and phloem in roots. Phloem is the other type of transport tissue. In eudicots the xylem usually forms a cross of cells within the stele which runs the length of the root.
Xylem moves water from roots to the leaves and phloem moves food from the leaves to the rest of the plant. In monocots the center of the stele is composed. Four independent phloem strands grow between each bar of the xylem cross. During transpiration water evaporates from the leaves and draws water from the roots.
The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves. They are the vascular tissues that transport substances throughout the plant. Xylem consists of dead cells. The function of the phloem tissue is to transport food nutrients such as sucrose and amino acids from the leaves and to all other cells of the plant this is called translocation.
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.
