W haley , W. G ordon (U. Texas, Austin), J oyce E. K ephart , and H ilton H. M ollenhauer . Developmental changes in the Golgi‐apparatus of maize root cells. Amer. Jour. Bot. 46(10): 743–751. Illus. 1959.—Golgi‐apparatus comparable to that of animal cells has been observed in electron micrographs of all cells of the maize root tips studied. The central structure consists of a “stack” of cisternae with the edges of which small vesicles are associated. In conspicuously vacuolating inner cortical cells the Golgi‐apparatus resembles that of dividing cells. The possible roles of these vesicles are discussed. As the cells of the epidermis and outer cortical layer mature these vesicles tend to accumulate and increase in size. In necrotic rootcap cells these vesicles are not apparent and the Golgi‐cisternae are hypertrophied.
