vessel



vessel defined in 1951 year

vessel - vessel (trachea);
vessel - Non-living element of xylem consisting of a tube-like series of cells arranged end to end, running parallel with long axis of the organ in which it lies and in communication with adjacent elements by means of numerous pits in side walls.

Component cells of a vessel, known as vessel segments, cylindrical in shape, sometimes broader than long, with large perforations in end walls. Functioning in conduction of water and mineral salts, and for mechanical support. Have evolved from tracheids, principal features of this evolution being elimination of multi-perforate end walls to form single large perforation, reduction or disappearance of taper of end walls and change from a long narrow element to one relatively short and wide. With few exceptions confined to flowering plants.
