Compare the roles of the endoplasmic reticulum and Golgi apparatus.

The endoplasmic reticulum is the three-dimensional membrane that runs through the cytoplasm and it also presents attached with the plasma membrane, nuclear envelope, and Golgi complex whereas the Golgi apparatus is made up of cisternae which is flat and expanded made up of protoplasm. The role of both endoplasmic reticulum and Golgi apparatus are related to each other. In the cell wall, the endoplasmic reticulum provides a skeletal framework to the cell which helps to give support to the cytoplasmic matrix whereas the Golgi apparatus synthesizes pectic compounds and polysaccharides which help in the formation of the cell wall. The protein which gets synthesized by rough endoplasmic reticulum is passed on Golgi apparatus, the cisternae of Golgi apparatus help to combine the protein with carbohydrate and form glycoprotein. The endoplasmic reticulum provides enzyme precursors to the Golgi apparatus which get packed in the vesicles of the Golgi apparatus and later after budding primary lysosomes get formed by the maturing face of cisternae.
