An excised fern apex and young leaf primordium when seen in polarized light show distinct multicellular domains of parallel cellulose alignment which reflect the successive segmentations of the apical cell. The superficial walls of the most recent apical cell derivatives show the effects of highly ordered cellulose deposition in which the microfibrils lie parallel to the newly formed cell plate.
