Fig. 13. Negatively stained transitional region lying flat on the grid, showing fiagellar surface coat (fc), flagellar membrane (fin) and the globular substructure of the outer doublets, and of the star pattern surrounding the basal cylinder. x 320000.
Fig. 14. Transverse section through the distal part of the transitional region. That part of the annular connexion lying between the outer doublets and the membrane is not homogeneous but contains densities placed in pairs (arrows) opposite each doublet outer projection. x 120000.
Fig. 15. Transverse section through the proximal part of the transitional region's basal cylinder. Doublet outer projections and paired densities are present, and Btubules knobs can be seen clearly in places (arrows). The flagellar surface coat is very well preserved. x 120000.
Fig. 16. Two mature triplet basal bodies still joined to each other by the distal striated connexion (sc) and to the plasma membrane fragments by transitional fibres (arrows). A developing basal body consisting of a cartwheel plus 6 singlets and 3 triplets is connected to the mature basal body pair by amorphous material that appears to be attached to fragments of the microtubular roots (r). x 120000.
