<span>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.</span>
Prokaryotes are organisms that hav only one cell and one nucleus while while Eukaryotes are organisms that hav many cells and many nuclei.
