WebEndoplasmic reticulum (ER) is an internal membrane that forms branching networks of many interconnected sacs and tubes. There are two types of ER: rough ER and smooth ER. The outer side (facing the cytosol) of the rough ER is studded with ribosomes. Under the electron microscope, the dense granular ribosomes gave the name “rough” ER. chunk loader in bedrock https://mazzudesign.com
