High resolution image of the cytoplasm of Tetrahymena. Mitochondria have tubular cristae, infoldings of their inner membranes. Peroxisomes, with a few tubular inclusions, mucocysts, and a planar view ...

High resolution view of the rough endoplasmic reticulum of Tetrahymena that sometimes forms large stacks or concentric circles from which other organelles are excluded. Peroxisomes lie nearby. EM take...

A view of the rough endoplasmic reticulum of Tetrahymena that sometimes forms large stacks or concentric circles from which other organelles are excluded. Peroxisomes lie nearby. EM taken on 6/21/67 b...

Fibers that splay out from a mid piece pass to the pellicle. TEM taken on 4/5/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 10,250X. Bar = 1µm. Published and adapted with permission from ...

Electron microscope autoradiograph showing radiographic leucine over elements of the rough endoplasmic reticulum. A few grains are also found over small, smooth surfaced vesicles of the Golgi complex...

High resolution overview of Opercularia coarctata with macronucleus, cytoplasm, and section of the oral area. Specialized rough endoplasmic reticulum with modification into decorated tubules that lie ...

Toxicysts in the cytoplasm of cross sectioned non-dividing Didinium. Toxicysts (extrusomes) are multilayered cylinders that are discharged from the cytopharynx region during capture of prey such as Pa...

Transmission electron micrograph of nucleus showing the characteristic features of glutaraldehyde fixation introduced as a primary fixative in 1962 and since used routinely. Chromatin appears differen...

Upper panel shows a transmission electron micrograph featuring the nuclear envelope with the nuclear lamina seen here as a uniform layer between the inner nuclear membrane and more darkly staining blo...
