Golgi vs ER in Electron Microscopy

[you.old]

How do you identify which one's which in EM?

ER is connected to the nucleus.

Yeah the ER is connected to the nucleus, so that mRNA can come to the ribosomes and be translated. The golgi is the trafficker that tells stuff where to go and is located outside the ER.

Nucleus -> rER -> sER -> Golgi -> membrane -> outside cell

Movement of material is seen (basically) in the order above, although the golgi can send things both forwards and backwards if extra processing is needed

Also the rer and ser are exactly the same thing. The rer is just the part that happens to have cytosolic ribosomes attached at that point in time.
