| Popis: | The ultrastructure of the red alga Gelidium sesquipedale has been investigated by optical, scanning and transmission electron microscopy, cross polarization magic angle spinning carbon-13 N. M. R. spectroscopy together with X-ray and electron diffraction analysis. After agar extraction, the thalli could be fragmented into their elementary cell components namely rhizines, medullary and cortical cells. Analysis of these cells after enzymatic and acid hydrolysis showed that a cellulosic microfibrillar network was one of the main components of their cell walls. A cuticle consisting of a proteinaceous membrane encrusted with cortical cells was also isolated and characterized when the thalli were exhaustively treated with cellulase |
