it is generally said that golgi apparatus works in the coordinate with endoplasmic reticulum. how?
Endoplasmic reticulum is an interconnected network of membranous structures like tubules, vesicles, and cisternae. Cisternae are the flattened disk-like membranous structures. Tubules are tubular in shape, while vesicles are sac-like structures.
There are two types of endoplasmic reticulum, namely smooth endoplasmic reticulum (SER) which involves in the synthesis of lipids and rough endoplasmic reticulum (RER) which involves in the synthesis of proteins.
The Golgi apparatus consists of a system of membrane-bound vesicles arranged approximately parallel to each other in stacks called cisterns. These membranes have connections with the membranes of ER (endoplasmic reticulum) and the material synthesised in ER is packaged and dispatched to various targets inside and outside the cell through the Golgi apparatus. Its functions include the storage, modification and packaging of products synthesized in ER into the vesicles for transport.
