General view and flagellar structure of Syssomonas multiformis (transmission electron microscopy, TEM). a General view of the cell section with flagellum and large anterior food vacuole (note that ruffled cell outline could be an artifact of fixation). b, c Arrangement of flagellum and basal bodies and their connection. d Twisting of the acronematic flagellum around the cell with nucleus and nucleolus. e Retracted flagellum axoneme inside the cell. f Basal body of the flagellum and nearest structures. ac, acroneme; ad, arc-like dense structure; an, flagellum axoneme; ds, dense spot; fb, fibril; fbb, flagellar basal body; fl, flagellum; fv, food vacuole; Ga, Golgi apparatus; mct, microtubule; mt, mitochondrion; n, nucleus; nfbb, non-flagellar basal body; nu, nucleolus; tp, transversal plate. Scale bars: a 2, b 0.5, c 0.5, d 2, e 0.5, f 0.5 μm
