Golgi apparatus consists of a set of membrane bound, fluid filled vesicles, vacuoles and flattened cisternae (closed sacks).
Cisternae are usually arranged parallel to each other.
The material synthesised near the ER is packaged and dispatched to various targets inside and outside the cell through the Golgi apparatus.
In some cases, complex sugars may be made from simple sugars in the Golgi apparatus.
Its main function is to store, modify, package and dispatch the substances.
It is also involved in the synthesis of cell wall, plasma membrane and lysosomes.
