Rough+ER

Rough Endoplasmic Reticulum
 * KEY TERMS**
 * Endoplasmic Reticulm-interconnected network of thin, folded membranes that produce,process,and distribute protiens.


 * Ribosomes-Organelle that links amino acids together to form protiens.

Unlike the Smooth Endoplasmic Reticulum(ER), the rough ER is studded with Ribosomes that send newly made protiens directly to the ER to be modified The difference between the Smooth ERand the Rough ER is that the Smooth ER does not have any ribosomes and the Rough ER does. That is also how you can tell the difference between the two if you were to look at a picture with no discription. As you can see, the Smooth ER has no ribosomes (green dots) and the Rough ER does. That is where they get the names Rough and Smooth ER.
