Explanation:

There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER), both are present in plant and animal cells.

The rough ER receives its name because ribosomes are attached to the membrane of the ER. It's inolved with the production, folding, quality control and despatch of some proteins. The process of protein synthesis starts when mRNA moves from the nucleus to a ribosome on the surface of the RER, the ribosome builds the amino acid chain that is then pushed into the cisternal space of the RER. When the proteins are complete, they collect and the RER pinches off a vesicle that can move to the cell membrane or the Golgi apparatus.

The main function of the endoplasmic reticulum is protein production. This reticulum has ribosomes, which are organelles whose main function is the manufacture of these proteins.

Explanation:

The rough endoplasmic reticulum has several functions in the cell, including the transformation and transport of proteins, especially in carrying them to the Golgi apparatus. This reticulum is also responsible for marking proteins with a signal within the lumen. In synthesis, the rough endoplasmic reticulum is the transport system used by eukaryotic cells for protein movement.
