The relative high absorption flux of the nutrients of spruce rootlets with secondary structures, in the basal direction, can be partly explained by anatomical consideration. Cells with lignified walls are included in the peripheral cortical layer. These cells are crossed by many pits. In the case of beeck, physiological measurements and anatomical observations do not agree completely. One has to hypothesize that the suberin walls of the cork cells, several layers thick, are more conductive to soil solution than previously thought.
