The rough ER
nucleolus is inside the nucleus and it makes ribosomes. Ribosomes are made up of mRNAs and proteins and it is the site for making proteins. There are ribosomes on some of the ER (endoplasmic reticulum) and so the ER is known as rough ER. As more proteins are made, they leave the rough ER via vesicles that bud off from the ER.
They are made up of Tubulin.
membranes
depends on what type of cell you are wondering about. look up a specific cell type and then the function of the smooth ER in that cell
Proteins are made in the ER and golgi, not the cytoplasm.
ER
processes the proteins made in the er
Smooth ER synthesizes lipid, while the rough ER makes proteins for the cell.
A rough ER (endoplasmic reticulum) contains ribosomes and ribosomes are the factories where proteins are made. :)

They are made up of proteins. They are globular proteins
Ribosomes are the structures found on the ER that manufacture proteins.
