A Network Of Membranes Studded With Ribosomes. A network of interconnected membranous sacs studded with ribosomes. The lumen contains flocculent material that represents a newly-formed protein. The endoplasmic reticulum in certain region of the cell may be devoid of ribosome particles. It is continuous with the outer membrane of the nuclear envelope.
The rough ER is studded with ribosomes giving it a rough appearance. The ribosomes that are attached to the Rough ER make it a major site for making proteins. The bound ribosomes of the ER synthesize proteins destined for secretion from the cell or that are to be incorporated into the membrane or into specific vacuoles. Endoplasmic reticulum ER is an internal membrane that forms branching networks of many interconnected sacs and tubes. Under the electron microscope the dense granular ribosomes gave the name rough ER. Rough ER RER is the endoplasmic reticulum attached to the ribosome and thus involves the formation and transportation of proteins.

It works closely with the Golgi Apparatus. ER tubules move dynamically on microtubules and form membrane contact sites with other organelles where membranes are. The endoplasmic reticulum in certain region of the cell may be devoid of ribosome particles. K - This extensive network of membranes is studded with ribosomes and functions as a surface for protein synthesis and transport of materials. Under the electron microscope the dense granular ribosomes gave the name rough ER. The endoplasmic reticulum ER is a network of membranes throughout the cell.
