Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen. When enough proteins have been synthesized, they collect and are pinched off in vesicles.

Answer 2

Answer:

Rough Endoplasmic reticulum:-

• These are the cell organelles present in eukaryotic cells.
• It is the store house of proteins.
• The structure is like the cistarnae .
• This structure increases the area of protein storage.
• The ribosomes present in the RER makes it appear rough.
• The main function of RER is the synthesis and packaging of proteins.
