Golgi apparatus transverse section

Figure 20-8 (A) Electron micrograph showing a transverse section through part of the Golgi apparatus of an early spermatid. Cistemae of the ER, Golgi stacks (S), and vesicles (V) can be seen. Curved arrows point to associated tubules. Magnification X45/000.276 Courtesy of Y. Clermont. (B) Scheme showing functions of endoplasmic reticulum, transfer vesicles, Golgi apparatus, and secretion vesicles in the metabolism of glycoproteins.

Fig. 2.7. Electron microscope (EM) picture of a transverse section of a root tip cell showing the nucleus (n), endoplasmic reticulum (er), mitochondria (m), golgi apparatus (ga), and an amyloplast (a). The point (nd) is a discontinuity in the nuclear envelope not a pore. The dark boundary region is the cell wall. (Approx. X 6000.) (From Whaley, H. G., Mollenhauer, H. H., and Leech, J. H., Amer. J. Bot., 47 401, 1960.)...
