Fig. 3: dikinetid with longitudinal sections of cilia and basal bodies

Dikinetids (see Lynn, Biol. Rev. 56:243-292, 1981, for discussion of kinetids in ciliates) are set in a shallow basin in the cell surface that has a fairly sharp rim at its margin. The basal bodies have a proximal cartwheel and a dense septum (not found in most bbs) just distal to this cartwheel. The terminal plate separates the basal body from the cilium that arises from the distal end of the basal body. EM taken on 5/31/69 by R. Allen with Philips 300 TEM. Neg. 14,800X. Bar = 0.5µm.
