Golgi apparatus are membrane-bound cell organelles. They comprise several flattened, sac-like structures called ‘cisternae’.
The ‘cis’ face of the Golgi apparatus is located near the endoplasmic reticulum, whereas, the ‘trans’ face’ is located near the cell membrane.
Cisternae are connected to the endoplasmic reticulum.
The ‘cis face’ of the Golgi apparatus receives molecules such as proteins and lipids from the endoplasmic reticulum. These molecules are modified, packaged, and transported to various locations.
