Answer:
A. Transporting packaged molecules from the Golgi apparatus to be released out of the cell
Step-by-step explanation:
Activities involving the production of substances like proteins occurs inside a living cell. However, these molecules need to be transported within the cell. Here comes the role of VESICLES. Vesicles are small structures inside a cell that deals with the storage and transport of molecules within the cell.
In this diagram, the small vesicles are transporting molecules from the Golgi apparatus, which is a cellular organnelle that functions in the packaging and modification of molecules like fats, proteins etc. In the diagram, the vesicle is heading towards the plasma membrane, which it will fuse to in order to empty its stored contents out of the cytosol.
