Caption: Xylem with pits. False-colour scanning electron micrograph (SEM) of a radial longitudinal section through wood of an ash tree, Fraxinus excelsior. Here, an empty thick-walled xylem tube known as a tracheid is seen, running top to bottom, formed from a single cell. Small round bordered pits (or pores) occur in the wall of the tracheid. Tracheids comprise the non-living element of wood and function in the conduction of water up the stem, as well as giving mechanical support to the tree. The pits allow the sap to flow across from one xylem cell to another. Magnification: x1,200 at 6x4.5cm size.
