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...

A segment of the edge of the axoneme showing the outer axonemal dynein arms that extend from the A-subfiber of a doublet to bind to the B subfiber of the adjacent doublet. TEM taken on 4/21/88 by C. S...

A high resolution of a quick-freeze deep-etch rotary shadowed replica of a parasomal sac from which a clathrin-coated preendosomal vesicle has pinched off. The typical clathrin cage structure is prese...

A view of an early endosome with at least two coated evaginations showing, lies next to the proximal end of a fractured basal body. Other clathrin cages may indicate other evaginations from the same e...

A clump of at least seven small clathrin cages that are probably connected to an early endosome (below the fracture plane). The morphology of these cages shows a tighter packing than the larger clathr...

Quick-freeze deep-etch of the contractile vacuole E-fracture face. This face like the collecting canal membrane is porous indicating that many IMPs have been removed from this leaflet during fracturin...

Quick-freeze deep-etch rotary-shadowed replica of a portion of the chemically-unfixed cytopharynx. The cytopharynx is continuous with the plasma membrane and is covered by only one membrane which is p...

The E-fracture faces of the plasma membrane and cytopharyngeal membranes are continuous but differ in appearance since the cytopharyngeal membrane is studded with IMPs while the plasma membrane has fe...

Details of the binding of the carrier vesicle to a microtubule. Four bridges, thought to be cytoplasmic dynein arms, span the 40nm space between these two structures. The membrane of the vesicle has b...

A freeze-fracture image of a DV-II transforming into a DV-III by rapid fusion of lysosomes with its membrane. The P-face shown here of the early DV-III has abundant IMPs as well as many inward blebs (...
