Woody Plant Tissue

Woody plant tissue. Daily Telegraph Sydney Big One Crossword Clue on 4 May 2017.

The answer is XYLEM

Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. The basic function of xylem is to transport water from roots to shoots and leaves, but it also transports some nutrients. The word xylem is derived from the Greek word ξύλον (xylon), meaning “wood”; the best-known xylem tissue is wood, though it is found throughout the plant.

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.[3]
