A view of the endosymbiotic Chlorella of a green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this image there is also an endosymbiotic bacterium. It ha...

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...

TIRF time-lapse imaging of EB1-GFP (green) and mCherry-tubulin (red). EB1-GFP is seen on microtubule tips that grow to the cortex but does not accumulate on stable microtubule bundles at the equator, ...

Scanning electron micrograph of a diatom showing the two silica based frustule (cell walls). Image also illustrates the regular pattern on the frustule.

Scanning electron micrograph of a fragment of surface of diatom cell. Diatoms have a silica cell wall also called a frustule that has regularly repeating features.

This figure shows the connection between the peristome and the food vacuole forming zone where the alveoli end. The cytostome is the opening that connects these two zones. TEM taken on 6/13/69 by R. ...

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...

The macronucleus is the largest organelle in the P. multimicronucleatum cell and can measure 35µm long by 12µm wide. A small fraction of a macronucleus is seen in this micrograph. The chromatin appe...

A high resolution view of a dividing Didinium nasutum. This large ciliate is capable of engulfing Paramecium. It has a thick ectoplasm containing numerous mucocysts embedded in its extensive epiplasm....

This figure shows the connection between the peristome and the food vacuole forming zone where the alveoli end. The cytostome is the opening that connects these two zones. TEM taken on 6/13/69 by R. ...
