Cyclotella meneghiniana cell wall visualisation. Scanning electron micrographs (a–d): (a) Valves (v) and girdle bands (gb) from deconstructed diatom frustules. (b) External valve view complete frustule 22 μm. (c) Valve margin showing process openings (po), silica granules (sg), and spines (sp). (d) Upper valve (v) with girdle bands intact (gb). Atomic force micrographs (e,f) illustrating C. meneghiniana’s true 3D cell wall morphology. (e) Valve face of complete frustule 7 μm, circle indicates area panel d enlargement. (f) 1.5 μm ×1.5 μm scan of cell wall alveolous.
