FIGURE 2.41 Scanning electron microscopy image of the reservoir region of Euglena gracilis, showing the
two flagella arising from the bottom of the reservoir. The arrow points to the thickened folding of the flagellum
membrane, typical of the transition zone (a). Transmission electron microscopy image of the transition zone in
transverse section, showing the characteristic star configuration (b). (Bar: 0.50 mm.)
