euglena is a mobile photosynthetic and photosensitive cell which dwells in fresh water. Euglena has an important evolutionary role, therefore its morphology has been and still is a subject of interest. The structures in Euglena which are involved in photoreception and signal transduction and transmission have been well studied. In this paper morphological and ultrastructural evidence of a single stable structure formed by the photoreceptor (paraflagellar swelling) and the other specialized flagellar structures of Euglena gracilis (paraxial rod) is provided using conventional and non-conventional SEM and TEM, on detergent treated cells, and on isolated flagella retaining their photoreceptor.

Cathodoluminescence (CL) in the scanning electron microscope has been applied to the analysis of germanosilicate preforms and optical fibres prepared by the MCVD process. While generally sensitive to the distribution of dopants, CL is an even more sensitive indicator of defects in these materials (such as those attributed to GeE' centres) introduced during fabrication. Some preforms manufactured under different conditions were analysed by CL to assess the influence of fabrication technique on the introduction of defects. Results indicate that CL could be useful for routine analysis of optical fibre preforms and for assessing the development of process control for optical fibre manufacture.
