Helicoidal structure and comparable texture variations

Abstract

With the aid of improved specimen preparation techniques in recent years, electron microscopy has yeilded increasingly more extensive and reliable data on cell wall architecture. For example for some types of cell walls, earlier published observations have indicated that microfibrils were in random orientation, but new techniques have shown that, within the lamellae they are in perfect parallel alignment over relatively long distances (e.g. Kishi et al. 1979).
