In the table at the end it says that osmosis moves down the concentration gradient, but unlike the other passive movements it moves from the lower to higher concentration gradient, so it confuses me a bit.

Why can't the vesicle from the rER go straight out of the cell? Why does it have to "stop by" the Golgi apparatus?

+Embla Frydenlund 'cause, as I understand, the Golgi Apparatus is like UPS, they change the protein that comes from the rER (if needed), therefore it will go exactly where it is needed. Like you have proteins in your blood and proteins in your lungs, but they do not perform the same job. So Golgi is the one in charge where the proteins inside the vesicles go. Google it for more information, I might be wrong

the golgi apparatus helps in making more complex structures of protein, like secondary or tertiary structures that cannot be made by the rER

in simpler words, plays a role in packaging the proteins
