In the meristematic and adult tissues of belladonna roots and shoots, the plastids contain electron-dense, roundish bodies, limited by a single membrane at maturity. Their ontogenesis has been followed in the different tissues, and a model has been proposed, according to which membranes with electron-dense contents, grouped to form tubular complexes, and isolated membranes with electron-transparent contents may be involved in the biogenesis of membrane-bound bodies. © 1977 Academic Press, Inc.

Abstract
In the meristematic and adult tissues of belladonna roots and shoots, the plastids contain electron-dense, roundish bodies, limited by a single membrane at maturity. Their ontogenesis has been followed in the different tissues, and a model has been proposed, according to which membranes with electron-dense contents, grouped to form tubular complexes, and isolated membranes with electron-transparent contents may be involved in the biogenesis of membrane-bound bodies. © 1977 Academic Press, Inc.
