The Golgi Apparatus in Plant Cells
During the early investigations there was little exploration of the possibility of the presence of the Golgi apparatus in plant cells. Several factors contributed to this situation. The early presumed analogy between the Golgi apparatus and the canals of Holmgren (1902) led to an assumption of equivalence between the Golgi apparatus and elements of the vacuome. This idea was supported in one form or another by Bensley (1910), Guilliermond and Mangenot (1922), and Guilliermond (1929). The association of the apparatus with secretion tended to de-emphasize plant cells, only a few types of which were recognized as secreting cells. Nonetheless, Bowen (1926) concerned himself with the question of whether plant cells contained Golgi apparatus. He developed an idea that the plastids might equate to the Golgi apparatus. This idea was picked up by Weier (1932) who gave credit for it to Bowen. Bowen subsequently undertook a detailed study of plant cells and concluded that he could demonstrate the normal components of animal cells and something in addition, to which he applied the term osmiophilic platelets which were much more demonstrable in certain tissues than in others (Bowen 1928). Having done so, he accepted the equivalence of these osmiophilic platelets and the Golgi apparatus.
