Abstract
A detailed quantitative analysis on the orientation of the cortical microtubule arrays and the last layer of cellulose microfibrils deposited in the secondary cell wall has been performed on Urtica dioica root hairs. It was found that cortical microtubules of individual root hairs show a preferential orientation, which ranges in the total root hair population from −20 to +20° with respect to the longitudinal cell axis. Immunofluorescence and thin-section preparations are comparable, as long as the individuality of the root hairs and the modal distribution of the microtubules in the root hairs are considered. The cellulose microfibrils in the secondary wall are organized in two steep helices
