An electron micrograph showing that a centriole is constructed from a ring of nine triplet microtubules. Most animal cells contain two to four centrioles. In longitudinal view, a centriole looks like ...

Figure 218 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The typical structural organization of mitochondria is revealed in this longitudinal section of a mitochondrion ...

Classic TEM. First description of the endoplasmic reticulum. Whole mount of unfixed, dried chick embryo fibroblast. Embryonic chick cells were grown on a thin collodion film supported by a fine mesh ...

Four centrioles imaged in one electron micrograph of a thin section, cut from a Chinese hamster fibroblast grown in tissue culture. The two centrioles that appear circular are the 'mother' centrioles,...

Centrioles multiply exactly once in preparation for cell division.In this remarkably rare image, four centrioles are seen in one electron micrograph of a thin section cut from a Chinese hamster fibrob...
