Fig. 44: Pca - microtubules guide the DV-IV to the cytoproct

A bundle of microtubules (arrow) that arises from a basal body adjacent to the cytoproct (cyp) comes to lie along a spent DV-IV. The assumption is that movement generated by molecular motors propels the spent vacuole toward the cytoproct. EM taken on 6/1/73 by R. Allen with Hitachi HU11A TEM. Neg. 12,750X. Bar = 0.5µm. Published in J. Sell Sci. 14:611-631, 1974.
