Softwoods lack specialized vessel elements (Tracheen) and conduct sap almost exclusively through tracheids (Tracheiden), whereas hardwoods possess vessels for sap conduction. Softwoods contain complex compound vessel pores (Poren), whereas hardwoods consist exclusively of homogeneous longitudinal tracheid cells. Hardwoods possess resin canals (Harzkanäle) throughout their sapwood, whereas softwoods lack resin-secreting epithelial cells entirely. Softwoods have a cellular structure composed primarily of libriform fibers (Libriformfasern) that provide mechanical strength, whereas hardwoods rely on scalariform tracheids.
