During division new basal bodies develop accessory fibers and begin to move apart to take up a position equidistant between the older complexes. The new kinetodesmal fiber seems to be associated with ...

Contractile vacuole pore in face view illustrating the microtubular ribbons that extend from the pore to the CV membrane, the coil of microtubules that surrounds the pore and smaller pellicular pores ...

Fully formed trichocysts are moved from the cytosol to the cell surface along microtubules. In this image a bundle of microtubules arising from the proximal end of the basal body lies against the tric...

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...

Detail of the filamentous reticulum along the left side of the cytopharynx from which cytopharyngeal ribbons arise next to its nodes. Quadrulus associated ribbons lie between the filamentous reticulum...

In quick-freeze deep-etch micrographs it is not easy to distinguish peroxisomes from surrounding organelles. The organelle at the top of this micrograph may be a peroxisome based on its finely granula...

Detail of CV pore. Microtubules encircle the pore wall and other microtubules radiate out from the pore toward the CV membrane. TEM taken on 3/27/69 by R. Allen with Philips 300 operating at 60kV. Neg...

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 ...

A bundle of microtubules that arises from a basal body adjacent to the cytoproct comes to lie along a spent DV-IV. The assumption is that movement generated by molecular motors propels the spent vacuo...
