Fully formed trichocysts are moved from the cytosol to the cell
surface along microtubules. In this image a bundle of microtubules
(mt) arising from the proximal end of the basal body lies
against the trichocyst membrane along its entire length. The membrane,
in grazing section, and the electron-transparent zone are seen.
Transport appears to occur tip first along this bundle of microtubules
and moves the trichocyst in a direction toward the origin of the
microtubular bundle. TM taken on 4/1/83 by R. Allen with Hitachi HU11A
TEM. Neg. 14,750X. Bar = 0.25µm.
