Answer:
The correct answer is- Rough endoplasmic reticulum.
Explanation:
The endoplasmic reticulum is membrane-bound structure which divided into two parts rough endoplasmic reticulum and smooth endoplasmic reticulum.
Rough endoplasmic reticulum contain ribosomes on their surface which helps in protein formation. Rough Endoplasmic reticulum is the structure that is involved in the manufacturing protein which is secreted out to the cell.
When these proteins are made in RER they are transported to Golgi bodies where they get modifies and transported outside the cell of in the cell according to their destination.
