Figure legend

Fig. 1-8. Electron micrographs of Monosiga ovata(Fig. 3-7, 9) Interference contrast photographs of living cells of Monosiga ovata. 3. Longitudinal section of anterior end of cell showing general disposition of organelles. dictyosome (d) and nucleus (n), and arrangement of basal bodies with the interlinking bridge (b). The fibrillar rootlet (fr). associated with the membrane bounded sac (s), can be seen arising from the lower edge of the non-flagellar basal body (nb). Within the axoneme of the flagellum the central filament (cf can be seen proximal to the central microtubules (cm). Bar = 1 um .

Figure notes

A long, narrow, striated. fibrillar rootlet extends posteriorly from the lower edge of the non-flagellar basal body towards the Golgi apparatus. The second, non-flagellar, basal body is located at approximately right angles to the flagellar base and is connected to it by a fibrillar bridge.
