A high resolution image of nuclear pores in face view included in an overview of the cytoplasm of Opercularia coarctata. TEM taken on 6/13/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,80...

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 ...

Opercularia coarctata. Transmission electron micrograph of contracted cell body. This ciliate does not have rows of basal body/cilia over its whole surface but has cilia in the oral region and in a tr...

The image shows a slice through a 3D tomographic reconstruction of a mouse adenocarcinoma cell based on x-ray microscopy. Live cells were cryofixed by plunge freezing in liquid ethane and the vitrifi...

Figure 421 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Horizontal section through the apical cytoplasm of a Sertoli cell in the testis of the t...

The image shows a portion of a slice through a 3D tomographic reconstruction of a mouse adenocarcinoma cell based on x-ray microscopy. Live cells were cryofixed by plunge freezing in liquid ethane an...

A view of an early endosome with at least two coated evaginations showing, lies next to the proximal end of a fractured basal body. Other clathrin cages may indicate other evaginations from the same e...

Like other ciliates P. multimicronucleatum has two morphologically and functionally different nuclei. Shown here is the tiny micronucleus, of which there are four, during interphase of this cell. This...

This electron micrograph shows a cross section through the midpiece of opossum sperm. Filamentous cytoplasm underlies a scalloped membrane with regular variations in thickness, which gives it a corrug...
