Golgi apparatus are cell organelles found in the eurkaryotic cell. They are composed of three major structures:
1. Cisternae - a series of flattened sacs
2. Vacuoles - large rounded sacs
3. Vesicles - tiny vacuoles
It has a 'cis' or 'forming' face towards the nuclear membrane and a 'trans' or maturing face towards the plasma membrane.
The main function of Golgi apparatus is packaging of substances synthesised by the endoplasmic reticulum and their secretion at the cell surface.
