Vessel

Vessel [ Botany ]

Dictionary of botanic terminology - index of names


	An fluid conducting structure in most angiosperm composed by an axial series of cells that have coalesced to form an articulated tube-like structure of indeterminate length.

[ From Latin "vasculum" a small vessel ]

A vessel is a tubelike structure of indeterminate length of the xylem that consists of a column of superposed cylindrical dead cells (vessel elements ) whose end walls have been perforated or totally degraded, resulting in a continuous tube reinforced by rings and spirals of cellulose fibrils thickened with lignin. Its function is to conduct water and minerals through the plant body.
They are found in nearly all angiosperms and flowering plants.
