High resolution image of a tangential section of basal body pair (dikinetid) showing a connecting fiber linking the BBs as well as attachments to a kinetodesmal fiber, to postciliary microtubules, an...

A high resolution view of the tubulated CV membrane attached to ampullae 2, 3, 4 and 5 of the CVC. The tubules lie against the ribbon of microtubules as well as form a large mat lying inward (centrifi...

Secondary lysosomes in quick-freeze deep-etch images lie against the smooth E-face of a phagoacidosome (DV-II) membrane. The P-fracture face of one fairly large lysosome lies close to the DV-II but no...

Secondary lysosomes contain a fairly dense matrix in well fixed cells. The content of these lysosomes seems to be released as a package into the phagoacidosome when they fuse to form the phagolysosome...

Longitudinal section of a striated band lying superficially to an arm of the infraciliary lattice but not contacting it. A post is seen at the junction of a branch in the infraciliary lattice. TEM tak...

The infraciliary lattice in this quick-freeze deep-etched image consists of a meshwork of branching fibers composed of many subfibers. Basal bodies and trichocyst tips extend through the openings of t...

The cytoplasm of P. multimicronucleatum like all other cells contains a large number of organelles that are membrane bound. Membranes are used to compartmentalize and isolate metabolic and enzymatic p...

Quick-freeze deep-etch image of an unfixed and fractured mitochondrion. The tubular cristae average 50nm in diameter. Each cristae bears a helically arranged double row of particles with the particles...

The carrier vesicles dock with the acidosomes and then fuse with these larger vesicles before or as the vesicles dock at the nascent Digestive Vacuole. Thus the contents of the carrier vesicles are fi...
