vascular tissue
a tissue that transports water and dissolved substances from one part of the plant to another
Vascular tissue refers to the plant tissue responsible for the transport of water, nutrients, and sugars throughout the plant body. It consists of two types of cells known as xylem and phloem.
Xylem tissue comprises dead cells and is primarily responsible for the upward movement of water and dissolved minerals from the roots to the leaves. The xylem tissue also strengthens the plant body. It is made up of four different types of cells: tracheids, vessel elements, fibers, and parenchyma cells.
Phloem tissue, on the other hand, consists of living cells and is responsible for the transportation of sugars, amino acids, and other organic molecules from the sites of production to the other parts of the plant. The phloem tissue is also responsible for the transportation of hormones throughout the plant body. The phloem tissue includes four different types of cells: sieve tube elements, companion cells, fibers, and parenchyma cells.
Together, the xylem and phloem tissues make up the vascular system of the plants, which plays a vital role in providing structure and facilitating the transport of materials between the roots, stems, and leaves.
