In a cell treated with trifluoperizine (TFP), all stages of endocytosis and movement to the early endosomes and out of the early endosomes can be found. These steps begin at the parasomal sac and endi...

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...

An image of the pellicle of Didinium, in cross section of a non-dividing cell, has a plasma membrane with a distinct glycocalyx on its external surface and a flattened alveolar sac system. Under the a...

High resolution view of the contractile vacuole pore encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell ...

Quadrulus membranelle (4 rows of cilia) in the buccal cavity of Paramecium tetraurelia. Microtubules of the axonemes of the cilia and the triplet fibers of the basal bodies are labeled. Ribbons of mic...

A view of a part of the oral apparatus of Conchophthirus which reveals details of cortical structure. This includes one oral membranelle and three vestibular kinities as well as cytoplasm and cortical...

A high resolution image of a cell actively undergoing endocytosis that develops an extensive layer of vesicles and cisternae composed for the most part of smooth undecorated membrane. The uncoated cis...
