Quick-freeze deep-etch image of rows of carrier vesicles (cav)
lined up along the cytopharyngeal ribbons (cp mt). These
vesicles arise from early endosomes as clathrin coated vesicles and
are about 100nm in diameter. Vesicles lose their coats before binding
with the dynein motors that link them to the microtubules. They tend
to lie on the anterior side of the ribbons along with the discoidal
vesicles (disc). Carrier vesicles eventually dock on acidosomes
and fuse with these. Acidosomes are late endosomes. EM taken on
5/24/88 by C. Schroeder with Zeiss 10A TEM. Neg. 12,000X. Bar = 0.5µm.
