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 ...

The two CV pores of a cell. An impression of the helically wound microtubules are detectable in the right pore. TEM taken on 4/21/78 by R. Allen with Hitachi HU11A operating at 60kV. Neg. 21,750X. The...

Higher magnification view of the spongiome of the Contractile Vacuole Complex. The spongiome is composed of a three dimensional array of tubules that are continuous with the CV membrane. Many tubules ...

Basal body formation occurs most prominently in the equatorial region of the predivision cell. A new basal body begins to develop perpendicular to the mature basal body at its proximal anterior surfac...

Cell division in Tetrahymena occurs by lateral binary fission and results in an anterior proter and a posterior opisthe. Prior to division rows of basal bodies elongate as new basal bodies are formed ...

A high resolution image of the detail of cell surface structures. The cell is covered by the plasma membrane and outer alveolar sac membrane which is separated from the inner alveolar sac membrane by ...

High resolution image of the detail of the three fibers supporting a basal body. A striated kinetodesmal fiber extends anteriorly from the basal body, a postciliary microtubular ribbon extends posteri...

A high resolution image of cytopharyngeal rods, composed of microtubular bundles, form the wall of the basket. Rod lamellae are attached to one side of each rod. TEM taken on 3/13/69 by R. Allen with ...

High resolution image of cilia and cytopharyngeal vesicles containing a flocculent content of unknown composition which lie next to the cytopharynx and between the buccal cavity and what may be the n...

A high resolution, longitudinal section through one toxicyst and one bundle of microtubules (nematodesma) of the oral area of Didinium involved in the killing and ingesting of large prey. Didinium spe...
