transRough Endoplasmic Reticulum
- consists of stacks of flattened spaces lined with a membrane
⇒ surface appears rough ⇒ when viewed under electron microscope ⇒ due to presence of small round structures called ribosomes attached on its outer surface. ⇒ outer surface of RER ⇒ is consistent with nuclear membrane.
Function:
⇒ transports proteins made by the Golgi body for secretion out of the cell.
