High resolution image of cross sections of basal bodies at the level of their attachments to the kinetodesmal fiber, the anterior basal body is attached by a thin bridge. The proximal ends of one post...

The proximal end of the basal body is sometimes the origin of other single microtubules or bundles of microtubules that extend deeper into the cell’s endoplasm. These guide trichocysts, tip first, t...

A view of the entry to the oral apparatus of the green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this view the haplokinety and the polykinety of the ...

Receptor mediated endocytosis is a process in which extracellular molecules are taken into the cell via coated vesicles that pinch from the plasma membrane. In Paramecium the resulting vesicles fuse w...

This image of a cortical monokinetid shows the basal body as well as postciliary and transverse microtubular ribbons. Slender endosomal vesicles accumulate near the bottom of a parasomal sac which is ...

Cell sectioned perpendicular to the surface. The parasomal sac ends internally as a coated pit, coated with clathrin. Where the coated pit has pinched off a clathrin-coated vesicle is formed. When the...

A micrograph of Tetrahymena showing a transverse ribbon starting from the anterior right side of the proximal end of a basal body (out of section plane) and crossing under the pellicle to end under th...

A grazing section through the cell’s surface shows segments of six rows of cilia running across the figure sectioned superfically at the top and deeper into the cell as one progresses down the figur...

High resolution view of the bundles of microtubules that arise from along the elaborately woven blanket of the filamentous reticulum that covers the ribbed wall of the right side of the buccal cavity....

Cross sections of basal bodies at the level of their attachments to the kinetodesmal fiber, the anterior basal body is attached by a thin bridge. The proximal ends of one postciliary microtubular ribb...
