• Ribosomes are the site of protein synthesis and thus, RER are present in the cells which are actively involved in the protein synthesis and secretion. It provides precursors of enzymes for the formation of lysosomes in the Golgi complex. ... They are also known as granular ER. They are also called Agranular ER.

Answer 2

Answer:

The endoplasmic reticulum (ER) is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum (RER), and smooth endoplasmic reticulum (SER). The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae (in the RER), and tubular structures in the SER. The membranes of the ER are continuous with the outer nuclear membrane. The endoplasmic reticulum is not found in red blood cells, or spermatozoa.
