Secretion is the process by which cytoplasmic substances are segregated and transferred to the cell exterior, involving synthesis at the ER, modification at the Golgi apparatus, and transport via vesicles. The Golgi apparatus can be isolated and subjected to physiological and biochemical study. In the past decade, the Golgi apparatus or a functional equivalent has been established as a general feature of the eukaryotic plant cell. Discussions of the early controversy regarding the plant Golgi apparatus can be found in the review by Nahm and the articles by Whaley, Kephart & Mollenhauer, and Hrsel.
Secretion (90, 139, 140), used in the context of this review, refers to the process by which substances produced in the cytoplasm are segregated and transferred to the cell's exterior. Studies of secretion have provided an inte grated view of structure and function where the metabolic systems are local ized in several cell components (39, 57, 80,90, 117, 132, 138, 140, 147, 173, 181, 188,208) . These components include sites of synthesis (ER), sites of con centration and modification (Golgi apparatus), and vehicles for transport to the extracytoplasmic environment (secretion vesicles). Discussions of the early controversy regarding plant Golgi apparatus can be found in the review by Nahm (127) and the articles by Whaley, Kephart & Mollenhauer (207) , and Hrsel (83). In the past decade, however, the Golgi apparatus or some functional equivalent (73) has been established as a general feature of the eucaryotic plant cell (29, 76, 8 1 , 111 , 165, 200, 207). This participant in the integrated processes of cellular secretion can be isolated and subjected to physiological and biochemical study.
