Answer:
The correct answer will be- Rough endoplasmic reticulum (RER).
Explanation:
The endoplasmic reticulum or ER is the enclosed flattened membranous structure present in the cytoplasm. The endoplasmic reticulum is continuous with the nucleus which provides mechanical support to the cell.
In the given question, since it states that organelle contains membrane-bound organelle which helps in the protein synthesis indicates that the organelle is a type of ER called rough endoplasmic reticulum which also provides compartmentalization of the cell along with intracellular transport.
Thus, Rough endoplasmic reticulum (RER) is the correct answer.
