Question

How would you compare the roles of the endoplasmic reticulum and the Golgi apparatus?

Answer 1

Instead of structural similarities, the ER is synthesizing site, while the golgy bodies are storing sites.

Explanation:

The ER like golgy bodies comprises an extensive network of membrane-enclosed sacs and tubules.
The endoplasmic reticulum is the largest organelle, from which golgy bodies are formed..
The rough endoplasmic reticums have ribosomes, while ribosomes absent in Golgy bodies.
Protein is synthesized on the endoplasmic reticulum, while it is absent in golgy bodies.
Golgy bodies are packaging organelle, while the endoplasmic reticulum is formation site of proteins.
