Cytopharyngeal basket in tangential section is composed of a complex
of microtubular rods. The lumen of the basket contains many vesicles
called cytopharyngeal vesicles. They may provide membrane for the
nascent food vacuole, lysosomal and/or lytic enzymes, or all of these.
Another role may be to provide vacuolar type ATPases (proton pumps) to
the nascent food vacuole. fv, food vacuole; bact,
endosymbiotic bacterium; spo, spongiome. EM taken on 3/13/69 by
R. Allen with Philips 300 TEM. Neg. 3,570X. Bar = 2µm.
