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 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...

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...

This group represents a serial series of sections. At the level of this section the macronucleus, cytopharyngeal tube, food vacuoles, and perioral membranelle are evident. TEM taken on 3/12/71 by R. A...

This group represents a serial series of sections. At the level of this section, the bottom of cytopharyngeal tube with one cilium remaining. End of macronucleus, three membranelles of the pek, and ma...

High resolution image of Colpoda. A soil ciliate and this micrograph is characterized by numerous mucocysts and food vacuoles containing bacteria in various stages of digestion. This electron microgra...

11 micrographs are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 3 food vacuoles (of a total of about 15 in the cell...

High resolution image of Halteria fixed in cacodylate-buffered fixative and stained. The round, dark bodies, possibly pigment granules, which were transparent in other preparations are electron-opaque...

Food vacuole and macronucleus of Didinium. The food vacuole contains unexploded trichocysts of Paramecium. Further details available at Wessenberg, H. and Antipa, G. 1968. Studies on Didinium nasutum....

A low power view of a median transverse section of a green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this view the abundant endosymbiotic zoochlorell...
