Was wir in pflanzlichen Zellen beobachtet haben, unter Bedingun- gen so genau wie möglich, führt uns zu denken, dass die so genannten Golgi-apparat forma- tionen in der Zytologie beobachtet nicht gut charakterisiert. In der Tat, sie sind meist durch den Einsatz von Methoden weit von spezifischen beobachtet, ohne Rückgriff auf andere Techniken und mit abmeldebestätigung aus lebendem Material. Unsere Forschung im Bereich der pflanzlichen Zellen deuten darauf hin, dass der Golgi-apparat (Geräte der Golgi-apparat, Holmgren, Cajal) d. h.

. The cytoplasm of the plant cell. Plant cells and tissues; Protoplasm. Chapter XVII — 199 Golgi Apparatus. what we have observed in plant cells, under as accurate condi- tions as possible, leads us to think that the so-called Golgi forma- tions observed in animal cytology have not been well characterized. Indeed, they have been observed most often by the use of methods far from specific without recourse to other techniques and with- out confirmation from living material. Our research on plant cells would seem to indicate that the Golgi apparatus (apparatus of Golgi, Holmgren, Cajal) i.e., the network, might often correspond to a vacuolar system like that in plant cells, whereas most of the dictyosomes obtained by osmic methods must be put into the cate- gory of vesiculated chondriosomes. (An opinion recently formu- lated by FiLHOL is that some dictyosomes correspond to differenti- ated chondriosomes, doubtless destined to play a role in the secretions of the cell). In reading the reports of some cytologists, one has the impression that they are re-discovering the chondriome under the name of Golgi apparatus. The so-called Golgi appa- ratus in plant cells:- It is clearly demonstrated, at any rate, that the Golgi apparatus does not exist in plant cells. If we pass in review the vari- ous work on cells carried out with the idea of finding a Golgi apparatus, we see that all that has been described as such corresponds either to the vacuolar system or to the chondriome (chondriosomes and plas- tids). Thus Sanchez, Luelmo, GoNgALVEs da Cunha, Zirkle by silver methods and Miss F. M. Scott by osmic methods, obtained superb Golgi networks which correspond to the vacuolar system in its filamentous and reticulate phases and which, more- over, are considered as such by these authors. Drew, on the contrary, figured in the root of Allium Cepa under the name of Golgi apparatus, elements obtained by silver methods which it is easy to classify with the chondriome (chondriosomes an
