Question

Write short notes on xylem vessels and tracheids.

Answer 1

• The xylem, vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. The system transports water and soluble mineral nutrients from the roots throughout the plant.

Xylem vessels - The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels. Xylem also contains two other cell types: parenchyma and fibers.

Tracheids - The tracheids are imperforate cells with bordered pits on their end walls. Tracheids are chief water-conducting elements in gymnosperms and pteridophytes. The conduction of water and mineral salts takes place through the bordered pits. They also offer mechanical support to the plants.
