Summary
Polyribosomes appear to be associated with the forming faces of plant dictyosomes, though it is difficult to demonstrate conclusively because of the lack of positional markers. InEuglena gracilis, a much clearer positional relationship between dictyosomes and ribosomes is visible. Here polyribosomes are aligned in a space delimited on one side by endoplasmic reticulum and on the other side by a dictyosome cisterna. The associated cisterna of endoplasmic reticulum is always rough-surfaced and spaced a uniform distance from the immature face of the dictyosome. The Golgi apparatus-associated ribosomes may synthesize some of the proteins specific to the Golgi apparatus.
